The first interview (phone screen) was with the recruiter which went more than well. The second interview was with what would have been the supervisor, again went really well. After ghosting me for a month I was contacted for another interview (number three). Again, went really well and was told I was advancing to the next interview and their would be another interview after that. To clarify 5 interviews before an offer would be extended. After being told I was being forwarded to the 4th round of interviews I received an email that I was no longer under consideration. Quite an interview process to be honest. They are definitely in it for the long haul.
