I applied thru campus career fair.The send an email to invite a phone interview next day,asking about some knowlegde about linux and C/C++, and big data processing experience. I messed up some linux questions, but the interviewer invite an engineer from another team,may be on front-end to call me two days later, asking me some UI/PHP project experience.

I applied this job from the university career fair, the interviewer reached out to me a few month later. The next is a phone call interview which ask me about some basic questions. A few days later they asked me to attend their on site interview. The working environment is pretty good and people there are friendly. The interview questions are not very hard.
