First stage was a one hour video call with two interviewers.
Second stage was a 4 hour monster interview with various stages and various staff members (intros > 2 of core dev team > portfolio review > design exercise on whiteboards).
I thought it went really well, but never received a single bit of feedback, despite back and forth emails with the internal recruiter. So to this date I have no idea if they offered me the job or not!
I took a half day off work and prepped a good while before this. I felt it incredibly rude and unprofessional to be ghosted in this way.
