Well that's your problem, your attitude. I would kick you out of an interview with that comment and make sure you would not be allowed to interview for the janitor position.
In the last decade I've never had my age, gender or race work against me or even be mentioned in an interview.
I've been offered jobs based on my personality and attitude. My first attempt at working for my current employer failed because at that stage I was not what they where looking for, 2 years later I got another chance and got a better job from them.
Attitude? Really... that it fact. It is difficult to get work in SA as a older white male. Been told before even though I scored the best in pre assessment tests and heard AA, BEE position...
And what planet are you from that you think I'm going to say that in an interview...
