I've received different advice regarding the interview introduction.
Regardless of the sex of the interviewer, in the scenario where the applicant is seated in the waiting area sees the interviewer coming towards them, the applicant gets up (does not wait for interviewer to approach), takes steps toward the approaching interviewer, extends the hand first, warmly smiles, introduces themselves first, ends the process with a firm handshake, and seamlessly makes small talk with interviewer as both walk side-by-side to the location of the interview (office or conference room).
It's a big production, but the reasoning for is that interviewers want to see how the applicant will approach patients, be professional, and make them feel comfortable and at ease.
