I understand that you're not always going to get the tbnt letter, but when the hiring manager emails you directly prior to the rejection and says "If you need to reach out feel free to send an e-mail." So I sent the hiring manager an email to gain information as to what I could have done better during the interview, or what prevented me from obtaining a dispatch position with the company so I can better prepare for the next opportunity or future opportunities. A week has gone by and I have not heard a word, this is an example of poor management even poor leadership. Good leaders/management won't keep somebody down. They will in fact helped others to be better. That being said maybe that shop might not have been a good fit for me due to the unprofessionalism of not being able to respond to a simple email.
