Reiterate your interest in the position and briefly mention a key point from your discussion that resonated with you. This not only demonstrates professionalism but also keeps you top of mind as they make their decision.

Manage Expectations

Be aware that the interview process may take time, and communication from the recruiting team may not always be prompt. If you experience delays or lack of feedback, remain patient and professional. If necessary, a polite follow-up can help clarify your status in the hiring process.
