Three "screening" phone calls and then three 45 minutes calls with their engineers - fairly chaotic / disorganized as they changed their mind mid-process about what position they wanted to interview me for. There were no computer science, algorithm, data structure, or deeply technical question at all. It was all things like "tell us about past projects you worked on". Then they ghosted me - I had to follow up with the recruiter to find out that they decided not to move forward. Very frustrating and disrespectful.
