Hi everyone!! I was recently laid off and had already accepted a full-time salaried role that starts next week. Since then, I received and signed a better offer from a large bank, but the bank's background check hasn't been completed yet and my start date isn't until early December.

I don't want to withdraw from the job starting next week while the bank's offer is still contingent on the background check. My plan is to work there in the meantime and resign before starting at the bank. I would not be working both jobs at the same time.

Could starting the first job while the bank is conducting its background check cause an issue?

Could the new employment automatically appear through a payroll or employment database even though I hadn't started it when I applied or signed the bank's offer?

Would I need to disclose the new job to the bank or background-check company? Has anyone done something similar, and did the bank question the short period of employment?…
