Interview was relaxed and informative. The purpose of the physical interview is to determine the individual's fit more than the technical aptitude of the individual. Unfortunately, they never really committed to hire. The recruiter expressed that he was waiting on an answer and that they wanted me on board. After a couple of months of that answer, I gave up and moved on. So, if you interview and they tell you they want you to work, don't miss other opportunities if you don't have a formal offer letter. This is true for any company.
