They contacted me in March and ghosted me for a whole month before scheduling the first interview. Then regrettably I attended eight (yes, eight!) video interviews over a span of several weeks. I had to take time off work to attend their virtual on-site which was a full day. The recruiter took an average of two weeks to respond after each round. I'd figure I had been ghosted but then I'd get an email from them asking to schedule the next interview. Even after the final round of interviews I had to send two follow-up emails before receiving a standard email rejection template from the recruiter. No response when I asked for actual feedback. For a company that claims to put people first, the interview process proved to be the most inconsiderate experience I've ever had with a potential employer. If you're thinking about applying to Mozilla, consider whether you really want to spend several months meeting half the staff and being dragged through interview purgatory. Hard pass.
