This was a two stage face to face interview process. First was a relatively informal, CV walk through and was one on one. I was then called back to do a 30/ 60/ 90 day presentation with a range of interviewers. In between, I was issued some online assessments but they were very quick and short (less than 20 mins between them) so I didn't mind completing them. They gave me some interesting feedback about my working style after I joined.
