I was invited to their site for less than half a day interview. No meal involved. The recruiter from HR welcomed me and showed me their offices and facilities. Then I was interviewed by several junior engineers for technical competence. They had similar engineering background as I did. Their questions were mostly about my previous experience at school and my skills. This part lasted for one hour. They left and presumably gave feedback to the recruiter. The next half hour was scheduled with the HR to evaluate if I was a fit to the company's culture. But this process was somehow canceled on that day. After a short moment of waiting in the conference room, I was offered an intern engineering position and I took it right away. I heard the full time process is much more intensive and similar to most companies. It may consist of a couple of days on-site interview with various group of people.
