Recruiter followed by hiring manager (CRO) followed by 2 other VP levels - all 45 minutes interviews. 4 in total which took about 2 weeks as recruiter was very good in keeping a good cadence and he was very responsive. Each interviewer (other than recruiter) was late by at least 5 minutes - first one had to push out 30 minutes.

Beware! They requested the submission of an extensive go-to-market business plan as part of the interview process. I declined. Not providing free consulting. Was declined. Interviewers were polite, although didn't ask particularly relevant questions to the role.
