I had a phone interview and was asked how I would approach a problem that the Surface team was actually facing. I believe they were trying to assess my problem-solving approach, how I would come up with test cases, and how I would zero in on the problem.

I was called on-site for the next round of interviews, where I met with all the members of the HoloLens team. It was only on the day of the interview that I learned I would be interviewing for a position in the HoloLens team.

One round focused on my resume, where they asked about every major project I had worked on. Another round covered embedded systems and calculations of bits/bytes and data usage per unit of time. There was a semi-formal lunch interview where I discussed my future plans, courses, and graduate life. The next two rounds involved C programming and puzzles. Each round lasted approximately one hour. Finally, I had the opportunity to interact with a senior executive of the department.

If there are battery-specific issues in a product after it has been shipped, and you have a partial idea about how and when the battery gets heated up, how will you try to minimize the issue? Will you use a hardware or a software patch approach?
