1hr Technical Assessment, then half-day of interviews consisting of debugging/refactoring code exercise (1hr), system design (1hr), behavioral (1hr), HR interview (15 min)
My experience varied by who I spoke with. Really enjoyed the technical assessment and my conversation with the developer administering it. Also enjoyed the interview with the hiring manager.
Felt the debugging interview was poorly designed. They ask you to download a zip with a program that implements the caesar cipher and debug some failing unit tests. But it didn't work, and I had to change from taking the test in python to taking the test in c#. The code is absolutely terrible and cryptic, and for the debug portion you aren't really allowed to refactor the code. They just want you to find the specific thing wrong with that one test. After 30 min, they begin the second part of that assessment and they let you start refactoring the code.
The system design interview question was fairly standard, though I feel the prompt wasn't clearly explained by my interviewer.
My worst interactions were actually with the in-house recruiters. Very unprofessional, and I was actually ghosted during my scheduled 15 min HR interview. Got a rejection email very late Friday (like 11:30 pm) night from him 3-4 days later.
