I had several rounds of interviews, including technical interview, case studies, and phone interview. Overall experience was good, people work there are really smart and intellectually curious, but the interview can be challenging.
Application was alright, no resume needed. Response came within 3 weeks. First interview stage was a set of coding questions even though role didn't expect you to be able to code. Questions could be solved e.g. in Python, data base questions in MySql.
