6 interviews - one face to face, the rest over a web conference with each about an hour with a range of dept heads (including the hiring manager) in the UK and the USA. Most were back to back and pretty quick. The downside was the feedback process. There wasn't one. I was the last candidate standing and found out they wanted to get more candidates in the frame. I was blanked after stage 6 and never got a formal thanks, but no thanks note. Disappointing experience.
