ITT Aerospace interview question

How to trouble shoot a problem, my abilities, how to handle grumpy people, and much more! I applied for a senior lead position then was told it would be for a tech 4 position 2nd shift. Then was told I would be the only tech on the shift, you could imagine the responsibility! Ive been a hands on manager for years and didnt mind the title as long as I was being compensated for all my skills and certs, in highly skilled and can do everything and anything thats put in front of me yet this company is unprofessional and don't have the decency to send an email that they had decided to go in a different direction!
