Ever back out of a accepted Job?

I've backed out of going to graduate school after accepting to go, which is similar to a job offering since they were offering a fellowship. The only thing I felt bad about was I didn't realize soon enough that I shouldn't go, but it just wasn't the right move for me. Some people may disagree, but I think you should back out of it. There are very few companies who would have qualms about firing you if they could find a better employee to replace you or would make more money by firing you. You shouldn't feel guilty about holding them to the same standard (i.e. you found a better employer or one who offers a better deal).

I've been on the other side of that several times - having someone who we tried to hire back out at the last minute. You look like an ass from that side too. I'm not trying to pass judgement (you gotta do what you gotta do), but it's likely you've burnt your bridges permanently with that company.

Yup did that this year. But I decided to stay at my current position.

Ha, my team in Seattle was going to get a new developer last week until he backed out at the last minute. That wasn't you, was it?

Ask if they would pay you better, let you do what you are going to do in that new position and give you a career path like the other offer would. If no, say you have something better.

It's just like any other business transaction. If the company wanted you not to bail out at the last minute, they would have signed a contract that stops you from doing that. Did they do that? If not, you don't have any obligations and a reason to feel like an ass.

Did you sign an offer letter? If so, you've probably burned that bridge and several adjacent.

If not, it's touchy and tender, but not necessarily a mark against you.
