Prof - Hello , Please introduce yourself .

Me - Introduced .

Prof - Given an array can you write code to find minimum and maximum of array .

Me - Yes Sir

Here is the code I had written -
int max=arr[0];
int min=arr[0];
for(int i=1;i<n;i++)
{
   if(a[i]<min)
      min=a[i];
   else if(a[i]>max)
      max=a[i];
}

Prof- Can you optimisze this code So that number of comparisons are reduced ?
Me - I started explaining Tournament Approach . In which total number of comparisons to
find minimum and maximum elements of array is (3n/2 -2) .

But the way I explained was
not very clear to interviewer . They kept asking me how you are approaching it . I told them
to divide the array into two parts of size n/2 then form min and max array . And then take maximum
from max and minimum from min . This part confused interviewers and the whole interview almost
revolved around this topic .
 
Prof - Can you write code to construct a node for Binary search tree .
Me - written .
There were some minor  mistakes I was doing while writing the code they pointed out and ask me to correct.

I used malloc in my code to which one professor asked

Prof- Why malloc is used ? What does this function do here.
Me- To allocate memory in heap for variables .

Prof - What does calloc function do ?
Me - It provides contigous memory in heap just like an array .

Prof- In this code can we use calloc instead of malloc ?
Me - Yes sir we can . (explained)

Prof - Now insert some nodes inside this BST . Explain algorithm only .
Me - Explained

Prof - Whenever you will insert any node do you have to change or update any internal nodes pointers.
of this BST ?
Me - No sir , Because this is a Binary search tree which is not required to be balanced . So each
time a node is inserted as a leaf node . So no need to update or change any internal nodes . If tree was
suppose AVL then updation is required .
 
I don't think my min-max approach was clear to them . Because even in last they were discussing about it . Professor asked me that are u doing pair-wise comparison and I said No in hurry .
After some instant one professor said that he is explaining same thing .

Prof - Okay , your interview is over now . Do you want to ask anything ?
Me - No sir.

Prof - It was nice to talk to you . We will announce results in next week. all the best.

Interview duration was around 30 minutes . Although I did some
mistakes as I was in pressure . But was very nice experience

We were shortlisted for the interview based on GATE score. There was no written test. The interviews were conducted on the 24th and 25th of May. There was a presentation before this where the HoD of the CSE department at IIT Madras explained everything about the MS and PhD programs and patiently fielded questions for about an hour.

They called me on my phone while the interview of the person before me was going on and told me to be ready. I joined in 10 minutes when they called again.

There was a panel of 6 professors out of which 3 interacted with me. The first professor asked for my introduction as is standard. The second professor shared a Codeshare link with me and began my interview. The question: write a function to find the top 3 (maximums) of a large array. The array is not pre-sorted and sorting is not allowed.

I asked if any time complexity requirements had to be heeded, and the prof asked me to go ahead and write a simple function. I wrote three loops, each to find the first, second and third maximums of the array. He expected me to have done it one loop, and started saying that I had a bug in my code, but then noticed the 3 loops and went “Oh. You’ve written three”.

He then asked me to do it in one loop. I thought for a bit and he gave me a hint: find the top 3 amongst the first 3 elements of the array and carry it on across the array. After a bit of light discussion, I wrote the right code.

After this, the third professor unmuted himself and entered the discussion. He asked me about my choice of linear algebra and I mentioned that I had selected graph mining as my research topic, which was under intelligent systems, so prepared linear algebra as the area needs it as a basic subject.

P: What topics do you know in linear algebra?
Me: Elimination, rank, subspaces of a matrix, vector spaces and subspaces, determinants, eigenvalues and eigenvectors…

(Unlike my IIT Bombay interview, this time I had come prepared)

P: Let's start with vector spaces. What is a vector space? What is a subspace?

Me: Defined both of them, explained their properties.

P: Is the zero vector part of a vector space?

We had a bit of back and forth on this, and then he asked me that since I mentioned that a vector space is described by the span of its basis, I could make the scalars $0$ and would get the zero vector, to which I said yes.

He mentioned how vector spaces have other properties and I suddenly remembered – mentioned distributivity, associativity, and he said yes.

P: Suppose we have a matrix equation $Ax = b$. $x$ is a column vector, $b$ is their product. What can you tell me about this?
Me: (reciting Gilbert Strang in my head) $Ax = b$ is solvable only when $b$ is in the column space of $A$.

P: Very good. So let’s suppose $b$ is not in the column space of $A$. We now want to solve an equation $A\hat{x} = p$ since $b$ is not there. We want to find a vector that approximately satisfies the requirement. What can you tell me about this situation? Is there a way?

Me: Explained about the concept of projections and derived the equations in chat.

P: Asked a bit more about this, and then asked – how do we know that $A^TA\hat{x} = A^Tb$ is solvable? How do we know the new vector is in the column space of $A$?

Me: Explained about how $b \ – A^T\hat{x}$ or something is in the nullspace of $A^T$ but muddled up what he was asking.

P: Gives a few more hints, asks what the null space of $A^TA$ is.

Me: It’s the same as that of $A$. But I wasn’t sure how that helped.

P: After a while, asked me to check about this offline. Moved to the next topic. Asked whether I can prove that the two nullspaces are equal.

Me: Provided a full proof based on both nullspaces being subsets of each other, which proves that they're equal. He gave me a small hint here too.

P: Wanted to wrap up in interest of time but said “I'll ask you one more question”. Gave me a scenario where we have a large matrix whose eigenvalues we calculated. You give this matrix to a friend and he returns it to you with $1$ added to all the diagonal entries. Will you recalculate all the eigenvalues of the new matrix or is there some other way?

Me: Clarified what he was asking. Then mentioned that recalculation isn't needed. If you add $1$ to the diagonal, it's as if you did $A + I$ where $I$ is identity. And in that case, the eigenvalues increase by $1$.

P: Can you prove this?

Me: Let $Ax = \lambda.x$. Now $(A + I)x = Ax + Ix = Ax + x = \lambda.x + x = (\lambda + 1).x$.

P: Was satisfied.

I thanked everyone and the interview ended here. Around 45 minutes in total (according to the time they called me to join).

We took a 3-hour test on May 2 which was conducted via remote proctoring. The test had 2 subjects extra besides the GATE syllabus – computer graphics and AI. The results were posted on IITB CSE dept’s portal the next day and while theory and computing systems got lesser than the max possible intake, intelligent systems received a lot of applications and they decided to shortlist more candidates in IS than their earlier limit, probably to make up for lesser candidates in the other two categories.

I was shortlisted for RAP and TA. My first interview was with the Cryo-electron microscopy project on May 10, and it was a disaster.

RAP

Prof Ajit took the interview. He asked me to give an introduction, what I’d been doing for the past few years after graduation, why I had selected the CEM project (I could not give a good answer), and then finally asked me a linear regression problem. At this point, I had covered only 15 lectures of Gilbert Strang’s LA course, and while I knew about least squares and projection, I could not give the satisfactory ML-style answer that he was looking for. In 10 mins it was over.

TA

Profs PB and PC took this interview on May 11. Nothing could have prepared me for it.

PC took my introduction, and then PB decided to start. They had actually read my SOP, or had it open at that moment, and asked me about my interest in graph mining. He then said let’s start with graphs (I had prepared basic LA and probability), and I knew I was a goner.

PB: What are Euler and Hamiltonian graphs?
Me: Answered

PB: Which problem is the harder of the two?

Me: Explained that Euler circuits can be checked by checking the degrees of the nodes in the graph. Hamiltonian was a known hard problem.

PB: Explain formally what you mean by “hard”.

Me: Tried to explain the concept of reductions but I could not remember the correct direction of the reduction (from or to known NP complete problems).

PB: Asked the time complexity of the reduction.

Me: Could not answer this one.

PB: Said that I should know the correct direction of the reduction, and that many get it wrong. Then decided to ask probability. Asked about the basic axioms of probability and what Bayes’ rule is and what it means.

Me: Explained these.

PB: Asked me about Naive Bayes classifiers and framed a Bayesian problem (“patient has blood vitals, you can consider them probabilities – we want to find whether he has cancer. How will you frame the equation”)

Me: Couldn’t do it because I had no idea how to write naive Bayes stuff.

I can’t remember what else PB asked me, but right after that, he said he was done in an authoritative tone (if he had been any more authoritative, I would probably have exited my own house chup chaap, forget about leaving the meeting).

PC started asking about linear algebra. I felt like I still had a chance.

PC: Asked about what orthonormal vectors are.

Me: Explained.

PC: Asked what the main property of an orthogonal matrix is.

Me: Got stumped. It’s $Q^{-1} = Q^T$. He then showed it through row-column dot product of the vectors during matrix multiplication. Safe to say I no longer felt like I had a chance.

PC: Shifted discussion to eigenvalues and eigenvectors. Asked me about what they are.

Me: Explained, although not straight to the point (should have just talked about $Ax = \lambda.x$ instead of saying $x$ is a vector in the nullspace of $A – \lambda.I$).

PC: Asked about geometrical interpretation.

Me: Explained about how it produces a new vector parallel to the earlier one. He said “scaled up/down versions of it” and I agreed.

PC: Asked me about eigenvalues of the inverse of the matrix. Asked me to prove my answer.

Me: Gladly proved how they are $1/\lambda$. Probably the only topic I got right in full.

PC: Asks what happens if the magnitude of eigenvalues is less than 1 and they are repeatedly multiplied with the vector.

Me: Obviously the term vanishes as we approach infinity. (this was probably about the diagonal equation and powers of a matrix – I should have said that n independent eigenvectors are required).

PC: Suddenly starts joking about whether I have lost touch with CS after so many years.

Me: I didn’t even know what to say to that.

Suddenly he stopped the teasing (it looked like he saw something on the screen) and asked whether my GATE score was of 2021. I said yes. He was serious for a few moments.

Then he starts joking around again that I should be careful with my answers. Asks me what programming languages I have worked in – I said python and JS.

PC: What kind of languages are these?

Me: At this point I was nervous enough that I said typeless – but quickly corrected to dynamically typed and interpreted.

PC: Is type checking done in Python and JS, as opposed to a language like Java?
Me: Tried to explain that Java is a compiled and bytecode-interpreted language and during compilation, it has a semantic analysis phase where types are checked. But Python/JS wouldn’t have that. Maybe the CPython interpreter would but not at the Python level.

PC: Tried to trick me on this, asked which is faster.

Me: Mistakenly ended up saying that the interpreted ones are faster – yep, an experienced guy saying this.

He had a big smile and told me to be careful before answering.

At this point they stopped the interview and I thanked them and exit. Took roughly 30 mins.

On 14th May in the evening I received the email for MS CSE interview which was scheduled on 17th May ( I just had 2 days to brush up my concepts and to finalise my fav subjects ! I stopped studying on a daily basis after my GATE exam in Feb :/ - I would recommend every candidate to stay in touch with their subjects ( if they are applying for MS ) as it will help a lot in their interviews )

At 3:30 PM on 17th May 2021 I got a call from IITI CSE to join the meeting via Google Meet. I entered the meeting :-

There were total 6 members present in the meeting ( their videos were off and they all were muted) and three professors questioned me in the interview - I would name them as P1, P2 and P3 ( I don’t know whether the other 3 members were professors or not … I didn’t even looked at their names for once, as I was already a bit nervous because it was my first interview )

P1 - Hi Priyanshu ! What are your favourite subjects ?
( I thought they would ask me for a introduction but they didn’t ... LOL :P )
Me - Sir Linear Algebra, Theory of Computation and Data Structures

P1 - Okay … Linear Algebra ( he seemed interested in it )
What are Eigen values and vectors ?
Me - Answered ( Gave both Geometric and Numerical Intuition )

P1 - How do we evaluate Eigen values ?
Me - Answered

P1 - What are the applications of Eigen values ? and later he asked the same about Eigen vectors !
Me - Answered

P1 - Then he asked me something regarding a matrix relation !
Me - I said I’m not sure about this and later on he simplified that problem and asked me again, then I was able to answer him ( I don’t remember that question exactly)

P1 - Do you know what is a Null Space and what can you say about it's dimensions ?
Me - Answered completely both Null Space and Column Space
( As I wanted someone to ask this :P )

P1 - What is a vector space ?
Me - Answered

P1 - Do the dimensions of column space and row space is same ?
Me - Answered ( even before he completed his question :P )
P1 - Prove it !
Me - Gave him some relations and he seemed satisfied !

P1 - What do you know about Matrix Norm
( I didn’t even heard this term before :/ )
Me - Sorry Sir !

P1 - What is a diagonalizable matrix ?
Me - Answered

{ He asked P2 to ask questions }
( and I thought that the interview was over :P ) – I couldn't hear him properly :/

P2 - So are you working right now ?
Me - No Sir, currently I am in my final year

P2 - Okay Priyanshu your favourite subject is Algorithms ... Right ?
Me - I repeated [ Sir Linear Algebra, Theory of Computation and Data Structures ]

P2 - Define me what is a algorithm in less than 5 words !
( He just wanted a short and precise definition I guess )
Me - Answered

P2 - Have you studied Computer Architecture ?
Me - ( I didn’t even saw my COA notes after my GATE exam )
But still I said -> Yes Sir !

P2 - What are the components of a CPU ?
Me - It was such a silly question but I panicked and said sorry sir :/

P2 - He repeated the question ( as he figured out that I panicked )
Me - Then I said Sir ALU, CU … He stopped me after ALU and CU

P2 - So every algorithm in general has two parts just tell me which part is handled by ALU and which part is handled by CU ?
Me - Answered one part correctly and later on he gave me a hint and I answered the other one as well !

P2 - Let’s talk about Complexity ... Why do we compute it in the very first place … What’s the need ?
Me - Answered

P2 - Let us talk about Complexity Classes !
( He asked me 2-3 questions related to NP class and other undecidable problems - I do got stuck in a question but he gave me a hint and then we were good :P )

[ He passed it to P3 ]

P3 - Priyanshu have you studied Computer Networks ?
[ Worst nightmare - I left CN for my GATE 2021 and I knew almost nothing that I can showcase in my interview and I didn't wanted to mess things up ! ]
Me - No Sir !

( P3 asked me whether it was in my CSE curriculum or not ? Then I answered that the semester in which CN was included got revoked completely due to covid last year ! )

P3 - Tell me what are planar graph ?
( I couldn't get enough time to revise graph theory in those 2 days ) – Drawbacks of not being in touch :/
I was able to recall a planar graph (figure) but just couldn't recall it's property specifically !
Me - Sorry Sir !

Then P2 said in between - Arree ... tell us what is a graph yrr ?
Me - Answered

P3 - How do we store them ?
Me - Answered

P3 - Which one is efficient ?
Me - ( Answered - both for dense graph and as well as for sparse graph )

P3 - Okay Priyanshu you can leave now !

No questions were asked from Theory of Computation ( not even a single question ) and what's worst - P3 wanted to ask some questions from CN (which I didn't even prepared for GATE 2021). Interviews will not go according to your prep/plan all the way long ( So, do revise those subjects which are related to your fav subjects ) You need to adapt to the situations and give your best ! As that's the only thing that you can do ;) And kindly be in touch with your subjects on a regular basis as I mentioned earlier - That will always help !

Take your time to answer your questions, don't be in a hurry !
The professors are quite friendly and they will help you out if you're stuck -
by modifying the problem or by giving some hints !
So, just keep your calm and give your best ;)

Verdict :- SELECTED

48

Firstly, there was an online written test on 11th May 2021. The test was in 2 parts:

Part 1:

In 1st part, there were 30 MCQ questions each with 1 mark and a penalty of -1 for each incorrect answer. The MCQs were of mostly GATE level. The majority of topics covered were DSA, Discrete Maths, Probability. Few questions were form CO, OS, CN and TOC (1-2 questions each).

Part 2: (Not used for evaluation and shortlisting, only for interview purpose)

Three subjective questions were there:

1) Let us assume, you are the head of Google and decide to build the next version of Google Meet. What features will you use/improve? How can you leverage skills from 3-4 CS subjects to improve the product?

2) There are 100 rooms in a hotel. The hotel manager is lazy. When a customer requests a room, the manager picks a room from 1 to 100 uniformly at random without even bothering to check whether it is already occupied. If the room is already occupied, the customer is asked to leave the hotel. Otherwise, they can check-in. Suppose that 100 customers try to check in, one by one, to the hotel. Show that the expected number of occupants is at least 50.

 

3)

 

I was shortlisted for the interviews. My slot was on 14th May 2021, at 10:30 am.

There were 3-panel members. But only two of them asked questions. I will address them as I1 and I2.

So the interview goes like this:

I1: Please give a brief introduction about yourself.

Me: Given.

I1: From which subjects you want us to ask questions?

Me: Linear Algebra, Probability, Data Structures.

I2: Ok Subham, let's start with the basics. What is eigenvalues and eigenvectors?

Me: Told with geometric intuition.

I2: Ok. Suppose you are given a diagonal matrix, what can you tell about the eigenvalues?

Me: The diagonal elements are the eigenvalues of the matrix.

I2: Prove it.

Me: Told an intuitive proof by the concept that the determinant of the matrix = product of eigenvalues.

I2: Ok. Now, lets move to probability. What are disjoint events?

Me: Told.

I2: Let's suppose you are given a probability of two events A and B. P(A) = 0.9 and P(B) = 0.9. Can you say that these events are disjoint events?

Me: Couldn’t answer. [The easiest question of the whole interview :)  ]. Due to panic, I couldn’t answer.

I2: Ok. Let's now move back to Linear Algebra. Suppose you are given 3 vectors of 2 dimensions. Is it possible that they are linearly independent?

Me: Explained with the rank concept.

I2: Referring to I1, would you like to ask any questions?

I1: Ya sure. So Subham, given a Binary tree, how can you find the height of the tree?

Me: Explained with recursion.

I1: What is the time complexity?

Me: Told.

I1: Ok we are done. You can leave the meeting.

Me: Thank you, sir.

 

They asked subjective test questions from some students. But they didn’t asked me.

VERDICT : SELECTED

 

Tips for future aspirants:

  • Don’t panic, they will give you enough time to think, just think freely.
  • Be sure you are good with each and every aspect of the subjects you are mentioning.
  • For written tests, keep in touch and keep revising your GATE subjects after the GATE exam also.

BEST OF LUCK…
