Crocs Team Leader interview questions

The interview wasn't difficult as I've been through interviews where they asked harder questions - it was just the ending made the whole process and experience difficult. First, I got there quite early and the person told me to wait for five minutes and it was about 15 minutes until I saw the manager. Anyway, so the manager asked me normal interview questions blah blah UNTIL the end when he asked me a personal question which I believe should NEVER be asked during interviews - stick to the job and the description and keep your comments and curiosities to yourself. I was taken back by the question as it was off putting as it was unnecessary to ask. I ran home and cried afterwards - such a HORRIBLE experience and now it makes my self-esteem go down because if the manager noticed it then that means other people look down upon it and makes me super self-conscious (not that I was already). I mean - I was born the way I am and having to question it just makes it seem that it's my fault but it's not; I can't help with being born the way I was. Anyway, out of all my interviews even with Fortune 500 companies such as Amazon, I have never had this experience ever.
