I really don't like this. The problem is that Yishan never explicitly states that there was an exit interview, and the reason for the termination was clearly explained.
He could have a half assed HR person that gave some bullshit reason like "you are not a good fit", and the ex-employee is legitimately confused about why he was terminated.
The other potential issue is that employees go into shock when they are told they are terminated, and are highly unlikely to remember the rest of the conversation correctly. People that get fired, generally aren't good at digesting feedback in the first place.
