Question 1
Before the interview, I thought the questions should be very easy because it was only an internship interview. However, obviously I was wrong and didn't perform well in the interview. Be prepared!
Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
First round with hr screening - 2 leetcode questions then hr manager screening then the loop which consists of 4 interviews each an hour long.
