One technical phone screening (not a phone screening with a recruiter, actual phone call with my hiring manager where he asked me basic technical questions, pass by reference vs pass by value, stack vs heap memory, object oriented programming, etc). Later I had an in person interview (they covered my travel expenses). The in person interview was a white board interview, writing out pseudo code for bit and string manipulation (from what I remember). Also asked to describe my senior design project in the white board. Also one conceptual object oriented programming question which I bombed.

The phone screen was them asking me about my experience and if I knew about certain web frameworks and databases they were using. The onsite interview was about 3 hours long with 6 people at the same time(them asking you questions simultaneously like a rapid fire round (in my case, it was 5 software engineers and 1 product manager). Questions started with the usual "tell me about a time when you..." and similar behavioral questions to assess team and company fit. Then they started asking technical questions. The first was finding errors in a java code that they give you in printed in a sheet of paper. As you solve this problem, you are also asked some object-oriented-programming questions. Then there is a leetcode medium type algorithm question that you have to code on the white board. Then something weird happens. They literally spit out names of almost all languages, web frameworks, databases, cloud services, etc. and ask you what you know about/think of/your familiarity with those technologies. And one person ticks the boxes in his paper as you answer those questions. And then about 20-30 minutes at the end is for the candidate to ask questions. I heard back in about 4 days after the interview.
