2 phone screens and 4 onsite interview which was a 2 hour process. You interview with the helpdesk team (2 people), the CIO, Director of IT infrastructure, Director of IT Ops manager. You should know O365 core apps but focus on Sharepoint and Teams but they themselves weren't very familiar with them but they are moving into it. I was perfect for the job and had a good interview process but did not get an offer.
