It's not just about the extra 7K plus the shorter distance.
- What about the career prospects in either company? If you're not talking about "career" yet, will the other company offer you anything that will make your CV look better? (certifications / experience / brand name)
- What about the people in the new company? You know the people in your current job, but what about the new job? I wouldn't want to lose my mates so as to enter a highly paid viper pit with everyone back-stabbing everybody else.
- What about the companies themselves? Any solid roadmap? You wouldn't want to join the one company that is doing very well right now but the CEO is short-sighted or has a(n apparently) totally wrong grasp of where the market is going. I'd stick with the company where the management was more insightful and knew what they were doing.
I saw this dilemma from the manager's side just two weeks ago.
I'm an IT consultant for a rail operator and I'm leading a small group of developers within the company, where we're essentially building its IT infrastructures from scratch (and that's LOTS of software, among other things). There's tons of work but the hours are flexible, the atmosphere is relaxed, friendly and informal, the salary is good and overall we're more friends than co-workers. Although this is Greece, the business outlook isn't *that* :) bad for anyone who stays as the consolidation plan we've been implementing is beginning to pay off and the boss knows what he's doing.
Just two weeks ago one of our developers jumped ship to join a big international company mainly known for its database product (and for upsetting the OSS community at large the last year or so :). Sure, it looks like a safe bet from miles away given the circumstances, but there are *always* pitfalls, so we wanted to make sure he had all the questions straight before he moved on. Hence, we had a very similar conversation to this, on a friendly, person-to-person level.
