I had an interview for assistant-manager for a big restaurant chain, this is a job I have quite a bit of experience in. I went to the interview thinking my job would entail planning and training staf, ordering, marketing, social media, finances etc. During the hour long interview I figured out marketing and training are centralised, finances is done once a week in the afternoon and ordering is done by the kitchen. I asked what I would be doing on a day to day basis and he described the head waiter position with a few administrative tasks. I wouldn't even be making the schedules, so I can't plan my own hours (which is normally a benefit from being the assistant-manager).
The guy told me to think about the job offer and contact him, but I told him then and there that I'm way too good at my job to work as a glorified head-waiter and they should change the job application to avoid attracting people that are way over qualified for what they need. I checked the job application and it's still online as assistant manager.
