I went through 3 interviews and declined on the 4th as I accepted another position. FYI all interviews are recorded (I'm assuming so they can reference and take notes post-call). First interview is a screening interview where you're asked a variety of basic interview questions. If you meet the basic requirements you move on to the next interview. Second interview is with the hiring manager. Talked about experience and role. General stuff. Third interview is the technical interview. Was pretty difficult as I don't have a strong programming background, but it covered javascript, html/css, python, VBA, and some other topics. Though this assessment is mainly to get an idea of your experience and there isn't really a pass/no pass. Fourth interview is a mock technical demo of a software of your choice. I had to cancel this because I had accepted another offer.
