#Feb23 #Interview Experience #Chennai
Hello friends !! Good morning..
This post is for those who may give ISRO interview in the coming months . I am going to share my interview experience in the below lines . I will try to cite the questions that were being asked to me as far as my memory goes.
My interview was scheduled at 3rd from the last. So I had lunch and Friday prayers then waited patiently and tried to stay calm and confident. It was roughly 4:45 pm when my name was called for the interview. So here the experience goes(I am mentioning the questions along with the answers which I gave) :
Interviewer : Introduce urself
Me : Introduced myself to all.Told about my graduation college and about my current job i.e. in BSNL.
Interviewer : Tell me about the subjects u have learnt in ur B.tech
Me : I mentioned Mathematics , Computer Architecture and Theory of Computation
Head Interviewer : What is Flynn's classification of architecture.Name them.
Me : Answered each of the types .
Interviewer : How does out of order execution occurs in pipe lined environment ?
Me : Answered.
Interviewer : What are the types of the hazards which are there in pipelining ?
Me : Answered.
Interviewer : What are the different types of data hazards ?
Me : Answered with elaboration.
Interviewer : What are the ways to reduce or eliminate control(branch hazards) ?
Me : Answered with elaboration.
Then questions on Maths were asked.They are as follow :
Interviewer : Explain about lattice.
Me : Explained properly
Interviewer : Some mathematical modelling problem.
Me : With a bit of hint from their side , I could come to the conclusion and answered rightly that it was related to bipartite graph.
Interviewer : What is Taylor's Theorem ?
Me : I clearly admitted to them that I was unable to recall as I studied about it way back in 2nd semester.
Interviewer : What is bijective and surjective function ?
Me : Explained
Then some questions about Theory Of Computation.
Interviewer : What are the types of grammars ?
Me : Answered and elaborated [ Type-0 to Type-3 ].
Interviewer : What is the practical use of regular and context free grammars ?
Me : Answered.
Other interviewer : Which programming language u r comfortable in ?
Me : I was very straightforward in this and told "C" bcoz I do not know each and every things of OOPS in C++ and also as far as Python is concerned , I know the basics of it only.
Interviewer : What r the command line arguments in int main()
Me : Answered.
Interviewer : To read or write from an arbitrary location from file , which function we need to use ?
Me : Answered(It was fseek() function)..
Interviewer : What does ls command do ?
Me : Answered.
Then some project related questions are asked regarding working and some basic terminologies behind it .
Interviewer : Tell me the pros and cons of collaborative and content based filtering .
Me : Answered .[My project was based on content based filtering]
Then the head interviewer took notice of the fact that I know six languages via the bio data form that they provided to fill prior to the interview.
Head Interviewer [In an appreciating tone] : How do you know so many languages ?
Me : Explained the reason behind each of them.
Finally some non tech question to conclude.
Interviewer : You are currently working in BSNL and that too in ur home state.. So what has made you think to join ISRO ?
Me : As a responsible citizen of our country , we are obliged to serve anywhere throughout the country.
Interviewer(Counter question) : That BSNL also does..So why ISRO ?
Me : Beyond doubt BSNL is also obliged to serve countrywide.But as far as ISRO is concerned , it is based on space science which has wider implications on the society.
[To add on] I got the inspiration to work in ISRO from Honble Late Dr. A.P.J Abdul Kalam with whom I interacted personally while I was in Class 10th..His zeal , simplicity and enthusiasm to work selflessly for the country has inspired me to move on..And hence if I am given a chance to serve ISRO in case I am selected , then I will give my best to serve my nation and the society.
The interviewers appreciated my answer and responded positively.The interview lasted for around half an hour.[By and large , others had around 15-20 minutes of interview].
In a nutshell , this interview was one of the nice interviews I ever had irrespective of the result which is yet to come..Though I look forward to it positively as the reaction of the interviewers was positive as far as I have felt.
All the best to you all..N plz pray for me as well so that I get selected in ISRO finally..
