The interview process was two hours long and consisted of several technical interviews.
I don't recall specifics, but nothing was beyond what you would learn in a mandatory CS curriculum for any of the technical topics. It also helps that the interviewers are very transparent about what they're looking for in your answers.
started with one technical round where interviewer asked me a lot of questions regrading my previous work and resume content. He dived deep into that and was satisfied with my answers.
Second round was with some senior guy who started with rapid fire questions. I answered most of them and he praised me by saying you have good analytic skill.
