Interviews at Microsoft
The Microsoft interview starts with several technical phone screens or they might require you to travel to one of their working branches. You will have 4-5 technical interviews with different teams.
The final decision belongs to the hiring manager. Commonly, this hiring manager is contacted only if you passed all the technical interview stages.
The main focus is on algorithms and data structures.
If you did not get any feedback after a week, then you should trigger a friendly follow-up e-mail to Microsoft contacts. Sometimes, it takes just a day until they provide a decision, but it can take a week, a month, or even more.
