Submitted resume at Microsoft's info session at my university.

Then, there was a 45-minute on-campus interview round, discussing my background and some basic technical questions.

This was followed by a day of on-site interviews at Redmond.

There were:

• Four technical interviews, each lasting one hour.
• One lunch interview, lasting two hours.

Some technical questions covered testing, strings, lists, trees, and brain teasers. They were not difficult.

The last interviewer asked some network and OS questions, which were unexpected.
