The position that I have applied is being advertised again. Should I be worried?
Should I be worried about this?


Nope. It is totally out of your control and impossible to guess what it means. It could mean they have already written you off and are just wasting time (and money) bringing you in for an interview. It could also mean that they are hopeful about you and need to satisfy some HR requirement. It could also mean lots of other things.
