Microsoft Senior Developer interview questions

A one hour interview with an engineer. He had an ill defined problem about a binary tree, and got frustrated when asked for more details about the problem. The solution was a simple recursive function, but he wanted you to walk through what it was doing and why. No feedback, just a generic reject email.

Everything went well and in a friendly manner. Good team of passionate professionals. Online interview, four stages, divided into two days. All in all, nothing out of the ordinary. Your technical experience, experience in a team, behavioral issues, problem-solving.
