The first round interview was a 30 min virtual interview which was set up on Microsoft Teams. It had mostly behavioural questions such as: "What do you think makes a good programmer?" and "What are some of the Microsoft technologies that you use" (this would have a follow-up to ask for an improvement upon that technology if you name one). This interview would end with a brain teaser/problem that you are given 10-ish minutes to solve. They may not necessarily be looking for the right answer, but they do want you to think the process out loud. The interviewer did a great job at making me feel comfortable and confident!

I applied through their website with a referral, after a month or so they sent me a home exam, I think about a month after that i had 3 interviews in the same day, each one around 1:15 hours.
