Companies generally like to hire from within because they can often pay below market average. Just treat those jobs as an internship, pad your resume, then start looking for better opportunities.

That works sometimes and backfires others. No shortage of companies that make the exact opposite call. "well the guy working in department A is more qualified than this outsider... but then we have to find someone to do the job in department A, an outsider lets us just replace the one piece that's missing".

I mean maybe it can work, I'm a 40 year old IT vet, every upward move I've ever made in my life involved switching companies. Bosses always tell me I'm too good at what I do for them to want me to move up.

Now maybe some do. obviously no matter what the advice we can find someone it worked for, and someone it worked against.
