Microsoft Intern Software Development Engineer interview questions

Was invited to a 1:1 interview at my college campus. The interview went well and I was forwarded on for a full day interview at the Seattle Microsoft campus. The date for that interview has been set, but it has not yet happened. In general, the interview process has been fine and the recruiters have been helpful, but the overall process has been slow.

I had a 1:1 interview with microsoft on January 18, 2012. I applied online and they invited me for a 1:1 interview on campus. It lasted for about 30 minutes. They asked me some basic questions about Why Microsoft ?, What made you take up Computer Science as your major ? and stuff like that. Then they got into coding questions. They asked me two questions. 1) Reverse all the characters in a string before you encounter an 'x'. abcdxdd - > dcbaxdd 2) Reveres all the words in a string before you encounter a word which has 'x' in it.
