Shashi Kant PandeyFresherSelected
Application
I was interviewed on-campus at IIT Roorkee for ISRO
Interview Process
Test Technical Interview
Round 1

Test

Interview Experience
It was CG based.
Round 2

Technical Interview

Interview Questions
  • Question 1: How does a mobile work?
Interview Experience
The questions generally asked are of general type and hence check how much do you know about different aspects related to the topic. For example: How does a mobile work can check your knowledge about various modulation techniques, protocols, disadvantages, comparison with CDMA etc. And you are expected to tell them all these things.
Interview Tips
As ISRO had a single round of technical interview for its selection process I tried to plan my answers for that. For example the most obvious question could have been regarding my area of interest. Think it carefully and prepare for the interview questions in that field.
General Tips
The interview process was completely technical as I have mentioned earlier. Being an IDD student they asked me what new have i learnt in this extra year. There were some questions from the courses that I have studied-one was from antenna and one from wireless networks. There were questions related to my project on GPR. Now, telling things which could impress the panel surely helps in any interview.

Pre-Placement talks - Yes & it helped me a lot in deciding the field in which I want to make my carrier.
Round 2

Group Discussion

Interview Experience
First there was a GD, among 35 people, from whom they choose 8 people for PI. We were 5 people in my group for GD. They left us to decide the topic for GD. We have to decide the topic in 2 minutes. The next 10 minutes was for actual GD & finally last 3 minutes to write the minutes of our GD on a paper.
Round 3

Other Interview

Interview Experience
Then there was first round of PI, from which they finalized 5 people. Then there was telephonic interview (only for two students, including me), but they were not satisfied by it so they went for 2nd round of PI. They gave final offers to only 2 people, including me.
Round 4

Interview Experience
I was short listed only in ISE. I gave my life's first GD-PI for ISE & I got selected.

Skill Tips
Don't forget to bring your eyes, ears & mouth to GD/PI. Eyes, to see other person/interviewer in the eye. Ears, to listen what the other person is saying & mouth to speak what you think is the best reply.
