Firstly I got a e-mail letter to ask me 6-7 questions about my quantitative skills. Then I was scheduled an interview with one of employees in this company. Most questions are about linear algebra and game theory. Then there's a second interview with CEO. This interview is more about personalities, or maybe just CEO want to see whether I am the person who I said in the resume. Finally I lost this opportunity.

I applied the intern from our university career center, and got the interview request just about one week later. There was a new program in that company and they need more people to work on it and could start as soon as possible. I just went to their company and had the interview. I enjoyed the time talking with the interviewer although I did not get the chance to work there.
