There is no private office in the test center, so you'll be interviewing in a lobby full of candidates, which is really awkward as they are sitting there witnessing the interview process.

The interview questions were pretty standard. I have done a lot of interviews in my lifetime, so it was a breeze. I spent 15 mins polishing and practicing for my interview. Most of the questions were asked via email and a few were asked at my in person interview. All the questions asked at the in person interview were questions that were asked via email.
