Well, both interviews went well. Got called thursday evening with an offer, which I verbally accepted. When I informed my current supervisor of it, effectively giving him a 3 week notice, he was displeased because he was losing one of his best people. They offered to match the pay of the offer, however, I had to tell him there was a training/experience factor as well. My current position, while its been a fantastic learning experience, doesn't advance my longer term career goals. One cannot be a help desk monkey forever. The new position allows me to work closer with server systems and get my feet wet in RHEL/Cent.
Throughout the day, I was in my boss' office twice and his boss' office explaining my decision. I was repeatedly offered the pay matching and they inquired if there was any position they could offer me to keep me to stay. Unfortunately, Linux doesn't really fit into their long term plans, so . . . yeah.
The new position doesn't come without its caveats, for one, it triples the amount of driving I have to do, and I'll be working nights for a while. Doubly painful, working nights means I have to do my running at the hottest parts of the day. In Phoenix. Arizona. Again though, it does come with a 7K increase in pay.
