Are you worried about being cheated or do you want to know why you chose a teahouse for an interview? Now that you have passed the interview, don't think too much. You said it was just a building, and it is understandable that there is no decent interview room (interview room and place). It is understandable that some companies choose teahouses for interviews, and there are also performances on TV. Don't make a fuss. Mainly depends on whether his attitude is serious and professional. You should carefully reflect the situation and process of the interview and look around him. Wish you get what you want!
