Usually wait until you have a written offer, have accepted it and any significant conditions are understood before resigning.

Background checks, visa approvals and start dates can create uncertainty; resigning prematurely can expose you to unnecessary financial risk.

A verbal congratulations call may feel final, but the formal paperwork and contingency language still matter. The date and procedure for resignation should account for notice periods, screening contingencies and your written offer.

Wait for the written offer and completion of material conditions, then check your notice obligations before choosing a resignation date. The consulting offer next steps can help you coordinate acceptance, background checks and a responsible handover.

I was tempted to resign right after the recruiter called.
