Email contact first, scheduled a 1-2 hrs onsite interview with 3 people, got noticed another day that the application was submitted to the hiring committee, then received an offer call in about 10 days

I gave my resume to recruiter in career fair. After two weeks, I had two phone interviews with two senior engineers from Yahoo and then got an internship offer. The coding problems is about implementing LRU, atoi and so on. And They also asked me some common knowledge about C++ and computer system.
