I had an offer from company A and another offer from company B offering +5k. Since I was more interested in A I asked them to match B's offer. They didn't and I had to reject their offer. Since then I had plenty of time to dig a bit more into what B is doing and further consider the situation and I feel that I made a big mistake, since career-wise A is going to be much better.
Is there any way to recall the offer rejection and accept the job (it has been two weeks since I rejected it)? I wouldn't mind if I had to interview again, but I am just worried that HR might consider it a red flag or something.
Edit: I got the job!
