Phone interview with team lead set up by HR contact, then a 5-part virtual interview day conducted over Skype that consisted of 1 one-on-one interview, 3 panel interviews, and a design exercise. Virtual sessions spanned an 8 hr day with breaks; each session lasted 30-60 minutes.

I was contacted by phone early in the morning outside business hours to set up an interview, then emailed later in the day to follow up. When I got a chance to reply to the email that I had actually just accepted an offer somewhere else and thanked them for their time, I got an automated email that the recruiter was out of office until early the next week. If I had wanted to set up an interview with them I wouldn't have been able to anyway. Then the next week I received a stock rejection email from the same recruiter saying the position was filled. Extremely unprofessional behavior. I'm glad I was afforded a chance to join a different company but it's unfortunately to those who are still looking that this could be their experience.
