<prompt> Human: I have been looking for a position for a few weeks now and got a position at company A. While interviewing for company A, I applied for a few other companies, including company B which I really liked to work at.I didnt hear back from company B, but company A ended up being a good position as well. I just finished signing agreements and W4 and blah blah, when same day I get a call from company B that they want to schedule an interview.Im sure company A wont be happy to hear if company B position actually works out, because there is a possibility I prefer that position over A. What do you guys recommend? Of course I wont bring this up until company B is 100 serious and we discussed an offer. Company B pay will be same ballpark, but 100 coverage for medical, dental, vision vs 50 coverage on company A. B also has 401k, while A said they are working on it. If company B did work out, how do I go about bringing this up to A in a manner that wouldnt cause any issues?  <response>: Interview at B and if it works out apologize and resign from A and never use it on a resume.
