Welocalize interview questions

During the group interview that I was in at the client's site, one of the interviewers told me to tell the group how old I was when I came to the U.S. to live and how long I have lived. As I was the oldest in that group, I was both stunned and upset a little. But I maintained myself cool and lived through it. But they need to learn that asking candidate's age is against the law.
