The process consisted of one HR interview, the preparation of a case study, 1 coding interview, and 3 technical interviews. The interviews were nice and stimulating. Scheduling the interviews was extremely slow. However, I am very unhappy with the interview process and the time effort required. The first HR interviewer did not show up. The last technical interview was initially moved to the next day, then delayed with no reason, and then cancelled. I knew about this only with the "No offer" communication.
