Do not rush to resign simply because you signed. Acceptance and employment start are separate from completing any required checks or contingencies.

The practical risk is giving notice before the new role is fully cleared. Read the offer conditions and follow the employer's stated process.

You can accept within the deadline while asking the recruiter when checks are considered complete and when they recommend giving notice.

Plan your resignation only once you are comfortable that material contingencies are resolved, subject to your own employment obligations.

I would test this in a couple of mocks with different partners. If the same feedback keeps showing up, then it is probably a real pattern.

I would keep a backup plan in mind, especially for anything involving recruiting logistics. It reduces the stress if the first option changes.

This is where keeping notes simple helps. I can see the logic better when I am not writing full sentences.

I had the same concern before recruiting. Once I practiced the exact situation a few times, it felt much less awkward.
