The interview was one on one. They asked typical questions for about an hour. The gentleman didn't seem exceedingly personable, and was very serious the whole time. After seeing his attitude, I wasn't sure that the company culture would be a good fit for me. They never contacted me to turn me down.

It's online interview. The interviewers are nice and polite, asking quite lot of questions but are still reasonable and try their best to answer my doubt and questions, overall good experience.
