Hello Everyone !!!

The written exam happened on 12th Jan 2020 and the shortlist for the interview came on 9th May 2020. I was not much confident about the ISRO examination result but I got shortlisted for the interview.

**Interview Experience :**

Date of interview- 10th – March -2021

Venue- NRSC Guest House Conference Hall, Balanagar, Hyderabad.

Time- 8:30 AM.

In the big reception hall, everyone was asked to sit and wait for their turn. At appx. 8:30 AM, they verified the documents and covid...

Since 2017 , I have been reading the success stories of many ISRO aspirants of CSE from various source and always had dreamed about writing a success story. I guess the day has finally arrived. Failures have been my constant companion , but it laid the stones to my success finally. Let me give you a brief background about myself.

I am Sandeep Nithyanandan. I am 2016 B.tech graduated from Sreepathy Institute of Management and Technology , a private engineering college in Kerala . I completed my M.tech in Computational Linguistics , from GEC Palakkad in Kerala in 2019. I have been working since then in a private firm.

There were different panelists with different domains, level questions keep increasing as you give the answers.

Q. What is BST?

Q. BST search complexity average and worst and when worst?

they’ll share a google doc with you to write on it as they can see it too.

Q. complexity of quicksort?

Q. write pseudo code for quicksort partition function?

Q write recursive call function of quicksort?

Q. Given this array, apply quicksort on this?

→ I totally did forget how to write...

Q. tell me about yourself ?

→ talk more about your projects, not anything else, they’ll simply ignore anything else. If you mentioned a lot of new technology in it, your interview might run on its way, for me, I kept it in the direction of what subjects I prepared.

Q. what subjects you prepared?

→ mostly DS, algo, OS, linear algebra is sufficient.

Q. What is Rank in a matrix?

→ some follow up questions on it

Q. What is BST?

Q. Explain NP problems?

Q. what is deadlock?

Q. how to remove deadlocks?

DONE.

**Platform:** Google Meet

**Research Stream Preference: Intelligent Systems (background subject: linear algebra and probability theory)**

There were three professors in the panel, only two of them asked me questions. I will refer them by I1 and I2.

I1: Read out my application, mentioned my GATE score and rank, department preferences, labs selected, and asked about my BTech CGPA

He asked me why I did not apply for direct PhD and explained me benefits of doing direct PhD.

I1: What are the subjects that you have prepared for the interview?

Me: Sir, I have prepared background subjects linear...

There is lockdown due to covid.

Ram and Gopal have decided to meet at a bus stop between 2PM to 3PM. At the bus stop a person can wait only upto 15 minutes.

If a person comes to the bus stop, he will wait for 15 minutes, or upto 3 PM, or till the other person comes up, whichever event happens earlier.

What is the probability that Ram gets covid given that Gopal is covid positive?

a. 3/4

b. 3/16

c. 1/4

d. 13/16

My interview was on Webex,Their were two professors in the panel.

professor 1:

1. tell me about yourself? ( told and i also told them about my fav subjects algo , os and linear algebra)

2.you are given an array of length 'n'. How will you find the maximum and minimum element in the given array.( they shared me a link , where I had to write the pseudocode of this.)

IITJ has above 600 cutt off for with fellowship Category or Via COAP- so I applied via self sponsored mode for CS and With out Fellowship for AI I got shortlisted for both categories and both interviews happened at same time.

Interview Experience,

1- Introduce Yourself ?

2- What is your preference CS/AI ?

3- Programming question-Find Second Largest Number in Array on Single Go(Single For Loop Logic) ?

4- What is Use of Pointers ?

5- What is Difference Between Primary and Secondary Memory ?

I received an email on 14th May from the program coordinator at IIT Indore saying that I had been shortlisted for the interview round. My interview was scheduled for 17th May between 2:30 PM to 5:30 PM.

Now, after my GATE results, I was a little heartbroken knowing that I wouldn’t make it to the IITs but I had consoled myself with the hope of getting into something like IIIT Bangalore. When I got the email though, I quickly realized that I was very ill-prepared for any technical interview as I had not studied anything GATE-related after 13th February. So I took a one-day leave from an internship I am doing and started going through GeeksForGeeks and...

Greetings to all, I am Animesh. I have appeared in GATE 2021 and my gate score was 742 with a rank of 447 General Cat. Here I am posting various questions asked from me in different interviews for MS/M.Tech Research courses.

Note: My interest lies in Machine Learning and AI, that’s why I prepared Linear algebra along with basics of ML for these interviews.
