The first round is a phone interview that takes 45 min. After several days I got the email saying that I wad invited to the on site interview in New York. There were two interviewers this time.

I applied online, and few days after, the HR email me to schedule a phone interview date with the interviewer, the first scheduled time nothing happen, so I scheduled another time, then the next time, the phone call came as expected, they only ask me some very simple questions such as what's the difference between java and C++, most of time I talking about my project which the interviewer seems interested in on it too. All seem going smoothly, however, two weeks later, I was told that the position was already filled.

Recruiter contacts me. It took 2 weeks.Interview questions are not hard.
