I had a phone interview for 45 minutes over Vidyo (recommendation download the app ahead of time I was late to my interview because of this) I was then invited to an in-person interview loop in San Francisco offices. Afterwards I was invited to a second in person interview loop in San Francisco. 3 days later I got an offer from Mozilla :)

Many interviews with different people, long process of interviews and they were slow in give feedback after the interviews and move to the next phase. For the last interview I was asked to give a presentation of a marketing plan to a group of directors.
