When I was studying i did a part time job in a hotel, which required a pre-employment medical from the company doctor.
For me this entailed all the basics, pulse, blood pressure, blood samples, height, wieght etc, as well as a questionnaire. A quick examination was done, but it did not involve nudity.
I asked some of the other employees about it - and for all the men it was pretty much the same. For the women however, it involved complete nudity, and breast exams. A double standard it seemed.
Another (female) friend of mine started working at another hotel at around the same time, and she told me she had a very thorough pre-employment exam with a "creepy doctor" - these were her words.
This old guy had her fully naked the entire time, spent a lot of time on the breast exam, and insisted on doing a pap smear. During the pap smear, she was completely naked and uncovered on the exam table. She felt very exposed and vulnerable.
Although he certainly acted professionally, she was freaked out by the experience, but needed the job so did not complain.
