A couple of calls with their HR person, an interview with a partner, a panel interview with a senior manager and another partner. The panel interview included a task that they sent an hour before the interview that you were expected to prepare and present. The first interviewer was nice and engaged. The panel were not. After dedicating significant time to the recruitment process, they did not even have the decency to send a rejection email (it has been months since last contact). They have reposted the job listing several times since I applied.
