Search Results: when to let go dream

So basically, I’ve been working at a very low level, customer service job at a large company for the past 2.5 years and I’m bored. Recently, I expressed interest in an internal coordinator job that I didn’t qualify for, and I was initially rejected. However, with some help from a few “cheerleaders” on that team, they are now trying to create a job for me that I would qualify for, and have even begun to give me training. Basically, I wouldn’t make much more in salary than I do now, because they’re creating a junior level position for me.. but it would be new challenges and obviously I get along with the people on that team. They’re currently trying to get the requisition number approved so they can interview me.

But about a month ago, I applied for a cool job outside the company. I was eventually called back, and passed the phone screening with both the recruiter and hiring manager, and have also had one on-site interview with the hiring manager. I guess it went well, because she’s having me back next week to meet more people. It would be a bump in salary too.

It’s basically my dream job, but I feel awful because my current company is cutting me major breaks by creating this position for me, and I don’t want to burn the bridge with them. Also, one of the people on the team has been letting me job shadow her every day for the past 2 weeks. So if I go for this other job, will my relationship with her and them be soured?

I would be honest and tell them I’m interviewing outside the company, but I also don’t want to let both opportunities fall through the cracks in case i get rejected from the outside company. So should I keep being dishonest, and keep job shadowing while I secretly interview for this other position? Or should I tell them? I feel bad, because they’re working to create this internal position for me, thinking I really want it, meanwhile I’m interviewing at other places.

Also, if you were me, would you stay with your current company or go to the new job?
