I've been offered an interview for a department transfer within my organization - basically to the exact same position, but working for another group on another project.
I'm happy with my current department, and I have no intention to take the position offered - but I've accepted the interview offer anyway, because I think it will be good practice for future interviews, and a good way to network with the other group.
But I am worried that if the interview doesn't go well, or that my lack of interest shows through, that it will sour my relationship with that group (which we regularly have to work with) and while it's not very far, it does take place in another building which I will have to take time off to visit.
My supervisor has already approved this request - but I'm wondering more seriously - was it a good idea to accept this offer? Should I interview with this group, even though I won't likely be accepting any offer they make?
Should I go to an interview I don't intend to accept the job (if offered)? is related, but this question is specifically for an internal position.
