You could easily miss the building if you did not know where to look. Service staff were friendly, and even engaged in small talk. Once inside and cleared security, the wait time was not a factor in any of the proceedings. First person I spoke to was very straight-forward and thorough. Second person who conducted the proper interview was kind, joyvial and really cared about everyone interviewing. In the seating/waiting area, everyone that was there were rooting for each other to pass and offered applause as successful applicants exited.
