It had 2 interviews -> 30 mins each.
First one, there were 2 interviewers. I got 3 coding questions with few db related questions as well. Pretty straight-forward.
Second 30 min interview had 2 interviewers as well. They were more focused on what you did in your previous job and the learnings out of both work and college related projects. Few behavioral questions.
