An in-depth interview by video call. I had already had an email explaining the process and the interviewer was very friendly and helped me to relax (I hate phone or video interviews). Lots of info given about the company and role as well as the usual questions about myself and my experience. Seemed great, but I had to decline the offer at this time as another opportunity arose for me. Again got a very friendly email wishing me all the best in my new job and told that I was welcome to reapply in future, should my situation change.
