I first had a discussion with the hiring manager and then 3 short interviews with 3 different people that'd I'd be likely working with regularly. The interviews were focused on cultural attributes -- growth mindset, customer obsesses, diverse and inclusive, and finally One Microsoft.

The Interview process was intense. I interview for the Bing Ads team and the questions were quite technical regarding experimentation and A/B testing. Focused on the publisher prespective and how the experimentation platform was built. Not much behaviourial questions were asked.
