less than 10 minutes, he was so worried about the survey I would fill out when I ended the interview, told me many times, ok is perfect and a son as possible you send the survey we call you with and give the schedule, I lost my time.
They asked about my basic background. It was a one round interview with the General Manager and was in person. They asked about availability and emphasized customer service. Also asked which part of the team you want to join.
I showed up on time yet waited in the lobby for the manager for about 15 mins. But it was short and sweet. They ask you basic interview questions. As long as you are competent, you have the job.
