Groupon Intern interview questions

I was Interviewed first with an HR. She asked me around 3-4 Questions and my interest. Questions were fairly easy. Next Round technical . The guy was an arrogant soul . He asked me questions like difference between multiprocessing ,multitasking,multithreading, he wasted around 35 min in those questions. It was supposed to be coding round in 10 min he asked me a programming question in which 5 min he spent explaining question.

The interview process is not bad if you are familiar with the genre. I was referred via by company recruiting operation. I got on phone twice with recruiter point of contact. The actual in-person part of the process included three consecutive interviews, each lasting 45 minutes long. They wanted to test out programming ability, frontend and design experience, and how to handle product development process.
