Microsoft Software Engineer - Internship interview questions

Talked to recruiters at a job fair. Got an email three days later for an on campus interview. Responded and signed up for an interview slot on their website. Interview was about 25 mins, starting off with a couple behavioral questions and questions about my resume. Ended with a short technical question, which the interviewer asked me to test afterwards.

1. ask me to write a method to convert "123" to integer 2. ask about "static" word of the method 3. other corner cases about this method
