Brief phone interview then in person. Interviewer discussed every aspect of the job including it's challenges. I felt like he was trying to sell me on it in many ways and also to discourage me from it at the same time. It was kind of strange. I am not particularly looking for a job in sales so I went in looking at it like a great practice interview. I would not take the position if offered because of the low base salary and hours required.

Took 2 weeks for 2 interviews, offer came a day after the second interview. The interviews were conducted in a 30 minutes time span. However, the recruiter seems to be seriously lacking basic understanding of visa sponsorship, resulting in the internship being revoked. I was about to decline it anyways. Be careful and make sure you get your points across, otherwise the recruiter would not make an effort to listen to you.
