Very relaxed and friendly interview. The interviewer had a sheet of paper with some basic, most common interview questions. He didn't liked them either, so we both had a good laugh. There was a role-play part at the end, which he didn't want to do as a role-play to not make it awkward, but just wanted to see how would I solve a problem. The problem was that a customer bought a phone "about 25 days ago" (actually more than 28 days ago), and the phone stopped working. So, he came to the store to return it (because there is a policy that if it stops working within 28 days and there is no physical damage, it is replaced by a manufacturer). As the manager was out on that day, I had to solve the problem. The idea was that I ask the customer for a receipt and check the date of purchase. As the 28 days passed, I told him that we cannot replace it, but I offered him to help him out myself, and if I can't help, we could send it for a repair as it's still under warranty. Basically, it was important that I solved it on my own and that I didn't tell him to come back another day when the manager is in, because the manager would tell him the same thing, as there is no other solution. I think this was the most important part of the interview, and the interviewer liked that I offered the customer my support on the spot.
