Interview was in 4 phases. All virtual. Initial checkpoint with recruiter, then three back-to-back sessions, a coding session, a system design session, and an interview with the hiring manager. Coding session was with two tech employees watching, create a library that processes args for a command line. First check what args are defined and to what value, then other conditions were added. Main interviewer was very soft-spoken so felt like I spent lots of time trying to get clarification on each step. System Design was create a system to process Credit Card charges to ultimately be validated against GPS info. Manager interview was pretty standard my impression I just didn't have deep enough experience in the areas he was asking about. I did get feedback afterwards which was rare but welcomed.
