I applied online through a job website and was emailed a request for a preliminary interview at their office in Houston. The first interview was very informal and took place in the coffee shop at the base of the office building. The questions were very broad at this interview, it was intended as an initial meet-and-greet to get a "feel" for potential candidates and lasted just under and hour. Once that interview was completed, I waited about a week to hear back about the second round interview. The second round interview was a series of several individual interviews. The were four sessions with 2 interviewers in each session asking much more specific job-based questions. Each session lasted about 30 minutes. Once this process was completed I waited to hear back for another week but was, unfortunately, not given an offer.
