I am currently working part-time in Customer Service at a grocery chain. I've noticed that a full-time desk job at our district office has been posted three times since June. This seems unusual for a role that shouldn't have such high turnover. I've applied each time, but only received a response for an interview during this third posting, and they contacted me in less than 10 days. I'm starting to wonder if this is a red flag regarding the position. Is it appropriate for me to ask why the job is open again? Also, should I inquire why they decided to move forward with my application now instead of the previous times?
