IIT Hyderabad M.Tech(RA Winter) Interview Experience

Hi, 

I got a call for M.Tech RA(Winter) on 19/11/2018 and Interview was scheduled on 26/11/2018. I applied using the GATE 2017 scorecard. My GATE 2017 score was 483 and rank 4611(gen). People having gate score 450+ was called(This is what I feel by talking to students there). Around 60+ people showed up. 

ROUND-1 

First-round was a written exam. Test Duration is 1 an hour. It started at 10:30 am. The question paper consists of MCQ type questions. 
Questions were based on C programming, Compiler Design, Analysis of sorting algorithms, Basic Machine Learning, Probability, Linear Algebra, DBMS, OS, etc. Other than basic ML questions all questions are like gate questions. Compiler Design questions were quite tricky. 

After MCQ round a pen and paper-based coding round was taken. It consists of 2 programming questions one of them is related to dynamic programming. Test Duration was 1/2 an hour 
(This was not considered for further shortlisting. They told us those who will be shortlisted based on the MCQ result. Questions may be asked in the interview regarding there approach to the coding problem)
