If someone who may refer you offers a practice case, it's usually a helpful opportunity rather than a hidden recruiting test.

They may be trying to understand your readiness before recommending you or simply offering support. Treat it professionally without assuming the person's feedback represents the firm's formal hiring decision.

A candid discussion of your case structure and communication can reveal more than a quick request for a referral. Don't try to turn the session into a pressure tactic.

Accept if timing works, clarify whether they mean a mock case, prepare seriously, and thank them for specific feedback. Keep any referral request separate and low-pressure.

That would make me nervous, especially if the referrer is senior. But I'd take the mock and be upfront about my level.

Would you ask for feedback after the case, then talk about the referral another day?
