Groupon

I had two 45-minute tech interviews on campus. Both interviewers were Chinese. The first one asked me a very complex question. The second interviewer's questions were satisfactory. As a result, I performed poorly in the first interview.

I contacted the team lead via LinkedIn when I saw that his LinkedIn status said "HIRING" and sent him my resume. He responded within a week and set up a technical phone screen and a coding interview. He asked some basic questions in Machine Learning,

The interviewer had no idea what he was interviewing me for. At least he was interested in my background, experience, or in me. He straight away jumped into coding, and we were done, of course, with a few questions which I asked in the end.
