Microsoft Intern interview questions

I had an on campus interview. They were very nice during the whole process. A Q&A session was held on campus the night before where you were able to become more comfortable with interview and the process. It lasted 45 minutes and was a 1-1 interview. The questions were very straight forward. Talk about your experience and past projects. Then a hand written technical question based on string manipulations without any api.

The interview started with personal questions about what i have done in the past year, then they asked me what was the most dificult thing that i have solved. Then they ask me to solve a relative simple problem and code it in a white papper, and then proceded to ask tecnical questions about my code. It was the first inverview of 3.
