Guys, there is no post regarding the gate 2021 set 1. So i thought of creating one.

So guys start commenting and share your experience regarding the gate 2021 set 1.

I am an ECE graduate gave GATE CSE 2021. This was my second attempt, in gate 2020 CSE i got 1645 rank and 52 marks.

My experience:I was in set 1 and felt paper was a little lengthy just because of the MSQ's .i saw set 2 analysis also, it was moderate and not that tough as some people are saying,  questions were doable but yes, 100% agree  that paper for set 2 was very very lengthy.But people are comparing it with 2006 paper and that's really wrong. Anyone who has practiced gate ques from 2006 knows that how tough 2006 gate paper questions were.

I personally feel set 2 was tougher overall than set 1 but not to the extent these online discussions are talking about.

how much are you guys expecting ???

 Lets hope for the best:)

 

EDIT: if someone want’s to see all the questions and their solutions then they can refer to the link provided by applied, i found the questions and the answers very accurate ,there are 64/65 ques from set 1 here.

Hi, since there was no posts on today's exam I thought I'll create one. I felt it was moderate to difficult and lengthy. What about you guys, how did it go ? Some questions were really easy but I felt if I had more time I could have solved them. Questions from COA were really really easy and some questions from algo and DL took time. I made some obvious silly mistakes because of the time constraints I had. My first mistake was jumping right into technical and saving not enough time for aptitude section. There were 12-15 MSQs . I think I might give GATE again next year with ample practice (which I didn't) I also took coaching from a pretty famous guy who sold himself and his channel recently.( which was a waste of my money and time. Some might have benefited but I honestly didn't. I found out about GO after I bought the course. This is my honest view and I'm just trying to create awareness amongst others and not trying to create conflicts.) Believe me GO is more than enough for anyone out there preparing for GATE. (Thanks @arjun sir and GO team)
P.S I had only 2 months to prepare for GATE. All the best for next year guys .

Nielit releases answer key of scientist B and Technical assistant post https://www.calicut.nielit.in/nic/

109

Just wanted to give some information on the GO Test series. Though about 200 people have registered for the tests, there have been less than 30 taken on average for tests. This shows that most of you are either postponing the tests or ignoring the subject tests.

  1. Actually the questions in subject tests are made to ensure no topic or question type is left out
  2. We have tried to include maximum twists in these questions so that it becomes easy in actual GATE
  3. Dont get demotivated by the marks – even 30% is good enough as long as you are understanding the mistakes and on second attempt you can score 90% or more
  4. Some people are scoring 80% or more in these tests and I hope them to make a top 30 rank in GATE.  
  5. So if you are postponing the takes the distance between you and the toppers are just increasing

From now onwards the tests will be live on every Mondays. There have been very good debates and hoping for healthy discussions to continue. Questions won’t be getting easier at least until the full length mock tests – where we shall try to simulate the actual GATE.

Hi Everyone,

 

I am Abhilash Bhardwaj ( https://www.linkedin.com/in/abhilash-bhardwaj-6000b7b4/ ), last time (DRDO- Advt -136 for Scientist-B) I was one of selected students for Scientist -B position in Computer Science discipline. 

 

I will include some of my experiences so that it can help future aspirants to crack this examination. I request you to read the entire post.

 

First I am including last year question papers:

 

DRDO CS-Paper 1   https://drive.google.com/open?id=13t9T291s2S2QCCC8qjCfBkzBCQGU3PNW 

DRDO CS- Paper 2  https://drive.google.com/open?id=13sbVEMqmndQZk9Wgcvz6tPoDJCPMy3ER 

 

Some suggestions related to Descriptive Examination:

  • First of all you must complete the entire gate syllabus, and don’t start with additional syllabus. Major portion consist of GATE CS syllabus except Hypervisor in OS and some other topics.

  • Now come to cyber security, Whatever syllabus is mentioned you can do them but last year trend reflect major element of network security like buffer overflow attacks, TCP SYN flooding attack, DNS spoofing attack, DNS Cache Poisoning, Man-in-the-middle, Ping to death attack, Denial of service attack, DDoS and many more. So focus should be given to them as well. (Soon I will try to make a consolidated list of attacks and issues.)

  • For Machine Learning , Last year asked questions on Simple linear regression, TF-IDF representation of Text documents, Overfitting and underfitting problems and some elements of classification problems. ML is a wide area, so you cannot cover each and everything. ( Here also I will try to make a list of topics you should read.)

  • Again, my request is to start with the GATE syllabus,  (GATE aspirants have only solved objective questions), here we need to solve everything like semester examination in a neat and clean way. Here questions can be like building CLR tables, proving using pumping lemma, writing code for Dining Philosopher Problem, Writing assembly language programs etc. So you need to change your strategy slightly. Rather than asking how many NAND gates required for XOR, they will ask you to draw it. 

  • For additional topics like ML and Security, interested people can contact me. 

 

I will post my DRDO interview experience after descriptive examination. 


 

Thanks for reading !!!

So let’s talk about M.Tech placements in IIIT A.

Before you question my authenticity , I’m the current placement coordinator of M.Tech at IIIT Allahabad so you are reading the most accurate stats and opinions.

Disclaimer : Note that the following answers are purely personal.

Question : What’s the average CTC of a M.Tech IT Student(2020 Passing out batch) at IIIT Allahabad?

Ans : Average : 14Lakhs.
Highest : 34Lakhs.
Lowest : 6Lakhs.
Median CTC : 11.75Lakhs.
Placed / Unplaced : 67 / 13

Question : Does that mean every student is making 1.16Lakh/Month (14Lakhs / 12 = 1.16 Lakhs) ?

Ans : No, that’s far from the truth. There is a huge difference between CTC and Net Monthly Take Home. For example, if a famous company offers 29.5 Lakhs in CTC, it doesn’t translate to 2.45 Lakhs/Month. The take home is somewhere between 1.14 to 1.20 Lakh/Month.

Question : Wait, where did the rest of the money go?

Ans : That’s where the game is. This company which offered 29.5Lakhs might be giving 16 to 17 Lakhs as Base Package(Take home per year) and 1 to 2 lakhs of Joining Bonus + Relocation Bonus (Paid one time at starting) and rest everything is RSUs or ESOPs which will vest in anytime between 1–5 years.

Question : I have heard B.Tech’s placement is great and M.Tech’s placement is shit, How true is this?

Ans : No, If a company has allowed M.Tech then they do not differentiate based on degree. They want to hire good programmers and many times M.Tech students could not compete with their B.Tech peers. However, things have changed this year to a minor extent. In my batch(2020) we had a few quality programmers who performed on par with B.Tech students if not better.

Question : Hey Sumanth! That’s all fine but not all companies allow M.Tech students, or do they?

Ans : Yes, not all companies allow M.Tech students. However all top companies starting from the likes of Amazon, Flipkart, Walmart, Uber, etc. allow M.Tech students sometimes even with higher CTC than B.Tech students. Out of around 140 companies that visited for the 2020 batch, M.Tech students were allowed to sit in 70+ companies. If you still think that 70 opportunities are not enough for you to land a great job, I would say be positive and focus on the opportunities available at hand rather than worrying. Even If you are a decent programmer I have got no doubt that you will work wonders and surprise yourself with the CTC you would draw.

Question : Fine sir. I accept now that there are enough opportunities however, are B.Tech students too strong with their coding skills ? Sir, do we even stand a chance against them?

Ans : Competition is strong. There’s no denying that, but no one ever has all the advantages. Let’s figure out ways to get those lucrative offers!

There are a total of 300 questions. Once you solve all of these standard questions, you will walk into an interview confidently knowing that you will do well.

Question : But sir, I have heard the course structure is hectic. Will we get anytime to work on coding?

Ans : Yes, the course is a bit time consuming compared to other colleges (24hrs of classes per week plus assignments on top of them), but my batch did very well at placements despite all this. Instead of being pessimistic, let’s use time smartly and balance academics + coding.

Question : Sir, my score is xyz and my category is abc. Can I get a seat in IIITA?

Ans : Please check the cutoff on gatecse website or CCMT website.

I have written the same post on medium and will keep on updating it as and when I get new questions. You can check that out too.

That’s all for now. If you have any further doubts you can reach out to me on facebook. I would like to thank my friend Bavani for helping me edit this post! :)

After GATE most of you will have one main question – where will I get admit. For this, last year cutoff is a good metric. But again many of the cutoffs are not available. Thanks to gatecselastrank.com most of the available details and also any relevant official links can be found. In this post I’ll quickly summarize some relevant information.

  1.  In 2019, for CSE all IISc/IIT except IITK/D were doing direct admit. (This does not include some related courses like IISc. AI, IISc CDS etc. and some new IITs where there were interviews). In 2020, even IITK will be doing direct admit.
  2. For Research admissions there are always interviews and this year also it should be the case.
  3. Expected last ranks for DIRECT ADMITS this year is as follows (after the last round and not the first round)
      Gen EWS OBC NCL
    IISc CSA 70-110 80-130 300-400
    IITB TA 70-130 80-150 300-400
    IITM/D/K/Kgp 200-250 220-300 450-650
    IITG/H/R 300-360 350-430 650-1000
  4. For NIT cutoffs you can see last year CCMT stats and convert the score cutoff to rank. 

  5. If you are general and your rank is 250-2000, you should be preparing for interviews as well as for IIITH/BITS

  6. If your rank is worse than 2000 and you are general, there is no good option available via GATE – you might get some lower NITs which is not worth going especially if you do not have good technical skills. IIITH/BITS are still an option.

  7. New IITs are worth going if you can find a good faculty to work under. Most of them may not have enough quality professors and placement setup also may not be properly established. If you are thinking about REPEAT please watch this video

  8. Regarding how to prepare for interviews, all the information you can get HERE thanks to Balaji Jagan and at the following links thanks to Lakshman Patel.

    13. https://gateoverflow.in/blog/9740/gate-cse-nsit-admissions

  9. For those not expecting any good admissions you have the following options

    1. Try for GRE

    2. Give exams like ISRO, NIELIT etc where the questions are a lot different from GATE and practice does translate to a good rank

    3. Try for CAT or MBA abroad

    4. Try for a job

    5. If you know how to get a good rank, you can repeat. Otherwise you can join a coaching and at least help run their business

    6. I’m not a life coach – I’m only passing you whatever information I have. Please do not ask me for advise.
