What kind of math questions do you ask? Are then relevant to the job? Is it knowledge that the employee will need to have for their day-to-day tasks? Asking math questions that are unrelated to the employee's tasks has strong bias for recent graduates. Ask a 40 year old a question about an equation they haven't used since they were 19 and they won't remember. I was once asked to do binary math on a phone interview. I hadn't had to do binary math since I was in school 10 years prior. I was pretty much guaranteed to fail. This was not a good test. If I needed it I could easily relearn binary math in a few hours at most.
