    Interview

    Internal recruiter very prompt and helpful. They gave a coding assignment. After that passed, then they conducted an interview online. Coding online with screen sharing on - very patient and helpful interviewer. Then onsite interview for the whole day to meet the rest of the team. More coding and questions on past experiences but no explicit behavioral type questions.

    Interview

    This is a on campus interview, the process of the interview is very straight forward, a guy look at my resume and ask about some detailed questions regarding it. Then we have worked on a question on a c++ question, which is simply find out all the prime number less than 65536. Then we discussed some web design skills which I've used in my projects. I think I did well, but didn't hear from them since then.
