Interviewed for a Scrum Master position with M3. The interviews themselves were ok. My issue was with the length of the interview process, which took over a month. The interviews consisted of a call with the recruiter, a call with the hiring manager, an in person interview with the hiring manager, then a panel interview, all of which were on different days. The company seemed great but if you are in a rush to find a job, this may not be the place to interview.
