How would you feel if your work had age discrimination? Well, the real question is how far you would go back into your work history. So if you’re the age of 35, but you want to work in a company where the age is an average of 20-28 years old, then you should use the formula called Amt, which is age minus twenty. This formula will bring up your job history from the past, and give you a better chance in the next job you want to apply for.
