Started with two phone interviews. Was then invited to come into office and meet. The in-office interview as about 3 hours long and was fairly redundant. Met with different stakeholders (individually) and was repeatedly asked the same questions. After the in-person interview I was told an offer was being drafted. Then I had one more in-office interview. Finally after the last interview they asked me for job experience collateral from 4-years ago. After all of that they never replied with a rejection or acceptance.
