It was an online round.
Basic aptitude practice and understanding of programming like data structure, C language was sufficient to get through it.
In this round 2 interviewer was there which made me bit nervous in starting but eventually it turned out to be easy going as they were asking question from my project and the subject like oop .
It was more like a viva kind of interview and not many algorithm based questions were asked.
This was bit tougher round.
I was asked algorithmic problems to solve and to explains the approach. It wasn't a big round but it was stressful.
In this round simple HR question were asked to me like hobbies and background information. Later he kept on asking question on the hobby which I mentioned. This wasn't a problem .
Being honest and not exaggerating yourself is important to gain trust and to keep our mind at peace.
