54,291 scientist interview questions shared by candidates

There were two rounds in ISRO. 1st is written test which is nothing but just for the screening purpose. Interview was quite conceptual. The very first difference I'd like to clear about between the private companies and government PSUs interview is that for private your focus should be more on programming and for government your focus should be more on concepts. At a time both are necessary. My interview duration was approx 55 min. There were 6 Senior Scientists in the interviewee panel. Each one of them was an specialist of a particular subject. Firstly, they asked me to introduce myself. As I've done my B.Tech. in CSE in 2011 so it took me bit long time to tell them about what I've done till now. And ultimately that made them curious about my profile as I've done CDAC certification (from gov institute) from BLR. After that I served an IT company (CGI Info Systems) for 2.2 yrs., n Currently I'm pursuing M.Tech. in Computer Science from IIT Patna. After that they asked me my favorite 4 subjects. So I replied OS Networking Maths DS After that they came to operating system and asked various questions from process and semaphore. Difference between process and threads. Difference between mutex and semaphore? In how many context u can differentiate them? For both questions first I explained basic differences then I explained from the perspective of implementation (in both windows and Linux). Then I told them how do they cleaned up in the system and also explained efficiency wise which one is better with their pros and cons. Networking Why TTL is there? What are it's values for different different systems like for windows, Linux, router? Working of traceroute command? It's answer is quite tricky, u can find on internet. How to set up router? This was from my previous company experience as I have mentioned networking related work in my last job experience. How routing table set up works? Now they started asking questions from M.Tech. What have you learned in your M.Tech. I told them only those subjects in which I was comfortable. They asked some simple questions from those subjects like what you have learnt in machine learning, where can you apply this and so on. My M.tech project was based on Formal Methods (semantic based procedure to find out the query similarity) They have done so many cross questions on my approach of finding query similarity. For some I defended very well but for some I couldn't make them more clear. At last they started asking questions from high school maths. They asked me geometry, this is the only section where I couldn't answer anything. Question: Draw two circles side by side and then draw tangent touching both the circles making an angle of 90 in between. Now what will be the equation to represent this. Then I request them to ask me math questions from GATE. Then they asked me linear algebra questions which I could answer after taking some seconds but not immediately. So overall experience was good. All the very best which you too can make!!
