Microsoft Software Developer interview questions

I applied online on Microsoft's job site by sending my CV in. A recruiter called me a few weeks later to say they were interested in interviewing me. They gave me a takeaway code challenge and scheduled time to go over it on the phone with a senior engineer on the team. Then after the phone interview a series of onsite technical interviews involving whiteboard coding, general problem solving and code observation skills.

It was an on-campus interview, the interviewer asked me about my projects and then asked me about how would I scale it. I was looking for a frontend position, so the question wasn't well suited for me.
