Microsoft

Starts with an assessment. After passing that, they scheduled back-to-back, four-round interviews in a day: * System design round (difficult) * Two coding rounds * One round on REST API implementation

The interview process included a phone screen with a recruiter and four technical interviews on site. The phone screen was mostly behavioral. When a technical question was asked, the recruiter simply wrote down the answer with no follow-up questions

There were 3 interviews (45 minutes each): one behavioral, one OOP, and one algorithmic. The interviewers were very nice and reassuring. Between talking and solving the tasks, I was also asked things from different subjects like Operating Systems.
