30 minute phone call with a recruiter, 30 minute phone call with the hiring manager, and about a 2 hour onsite composed of four 1-on-1 interviews with the hiring manager and 3 engineers/architects/directors.

The phone calls were pretty much the standard behavioral questions like, "Why Fidelity Investments?", "Tell me about yourself.", "What you'd like to do?", etc.

The onsite interviews were mostly behavioral questions, but there was one "technical" round. The technical round wasn't based on problem-solving, data structures, algorithms, teamwork, or any of the standard technical interviews you'd expect. It was just a bunch of questions on specific parts of technologies, and the expectation was that you would be able to read the interviewer's mind and respond with the exact answer in their head. Other than the "technical" round, the other interviews went pretty well; the interviewers were friendly, and the conversations were good.

Unfortunately, I do not remember any of the specific questions asked in the "technical" round. They were a bit ridiculous. No SQL/database, data structure, algorithm, concurrency, or programming language-specific questions were asked.
