1. why you choose bio tech branch?

2. why should i select you?

3. how you are benefitial for us?

4. do you have any questions for us?

You must ask a good question otherwise it will create a very negative impression of you in front of them. so many persons who didn't ask questions were rejected.


This is a combination of h.r and technical type they can ask you anything. The questions that they asked are following

 1. introduce yourself?

2. why bio tech branch?

3. what is the difference between c and c++?

4. do you have any question for us?
