Have you ever been rejected by your industry because of ageism? What was the reason?

In 2015, Mike, a friend of mine, had an interview with a company that needed an accountant. Apparently, despite his energetic, fun character, he was rejected because he was not relatable. Mike said that the moment he opened the door and said greetings to the interviewer, he felt that this was not happening. The interviewer didn’t care and listened to Mike’s answers and explanations. Mike also told me that the interviewer was asking the questions to do the process, not to find the right person; the interviewer had already made up his mind. The reason was unclear for us, but they would mention it rather than say he’s not relatable if they had any reason to reject Mike.
