I had 2 technical interviews and 1 HR interview in my on-campus placements at college. First technical round had most of the questions on data structures and algorithms. Second technical round had questions from networks. HR interview was lengthy but interesting. I was asked how I would react in various situations and some typical HR questions.

I applied for the position and heard back after 2 days. Had an in person interview at a conference and heard back within two hour. It was a really quick process and everyone were really helpful and friendly
