So I had a paid trip to Dallas where the interview happened. It was a back to back interview at the Dallas HQ of 45 mins each, 1st Behavioral interview followed by 2 technical interview and the final behavioral interview. The technical interview was really basic about windows but they did ask a lot of how to server this and that. The behavioral interview was quite easy but they did probe a lot as well. Overall it was an okay experience but I really loved how the recruiter planned and set up the interview. Good luck!
