So you went with your gut and made the call to reject the offer. For most people, that is a very acceptable reason to justify to your missing zeros on your paycheck. Right now you're perhaps wondering if you made the right decision -- afterall, Goldmans is creme de la creme no?
Like others have said, only you can answer that. Personally, I have a different take on this. I think early in your career (you sound like you're early in your career), it's all about an information land grab even if it means forgoing short term rewards (like a nice salary). The experiences you gain in the first 3 years of your career will have the most impact on the rest of your career and life. So, my question to you is: are you learning more at this company or do you think you would be learning more at Goldmans?
