Should you apologize for bad interview?
In this message, apologize for your poor performance, bad behavior, or missing information, and try to recover. This thank you may save the opportunity. OR, it may remind them when you were less than impressive and end any opportunity you might have had. Sending a standard thank you note might be a better idea. What do you say after a bad interview? If you have the time, I would appreciate the opportunity to speak with you again.
