A company whose offer I accepted is having a major technical issue with their online onboarding application which is preventing me from completely signing off on each of the tasks required. There is a complete lack of concern or ownership in getting it resolved which is wasting my precious time. Meanwhile I have open offers from other companies who were not my first choice but likely will not have technical issues along the way; each offer expiring at various times.
Canceling an already accepted offer is generally seen as bad and would harm one's reputation; however would this particular scenario be validation for doing so without repercussions?
