His phrasing definitely can be improved. But a lot of people in the reddit thread are incorrect. There is a difference between what is illegal and what is slimy. What the interviewer did is inappropriate but there is no proof that discrimination occurred.

I think it's unethical to hit on co-workers, direct reports and especially interviewees, but there are two people on my team who met their spouses during an interview at previous companies.

Edit: I don't understand the downvotes. The people asking her to lawyer up do not understand employment law. Unethical behavior doesn't automatically mean it's illegal. The definition for discrimination is pretty strict. Unless you can prove the interviewer has a pattern of rejecting female candidates and then asking them for dates then there is no case here.

The other point I wanted to make is there are people who date their interviewers. Does that mean it's not sketchy? No. But the success stories serve as encouragement for this kind of behavior.
