I got offered the financial analyst position for a big company that I wanted

I changed jobs in June. I was pretty much the only specialist in my field at that company but I didn't feel guilty. Businesses are just like football clubs. People talk about loyalty but these entities will move you on in a heartbeat if costs dictate that they need to. Business is business, it's not personal. Decent managers will appreciate that every employee has to do the best for themselves. We all have to put food on the table.

congratulations! Nothing to feel guilty about. You worked hard for them and they were lucky to have you. You don't owe them anything.

You shouldn't feel bad for quitting a job. The company will certainly not feel bad for letting you go

Never feel guilty for improving your job and or life. Make the most of it

Go for that new position. You did not do that immense amount of school work to stay at your current job. There is nothing to feel guilty about. You are worthy, go for it!

Congratulations, no need to feel bad, that's business. It goes both ways.

make sure to max out your per diem on the work trip

Congratulations!!

Συγχαρητήρια!
