Heard back from application within a week. Did a screening call with a recruiter, then 4 back to back interviews with team members approximately 30 minutes each. Interviewers were great for the most part, aside from one, which ruined the whole experience. Interviewer opened with how hungover they were and how much they didn't want to be doing this, and proceeded to be unresponsive, if not hostile throughout. It was possibly the least professional interview I've ever experienced.
