At a previous company we hired an 18 year old guy and father from a minority and without a high school degree. He could write enough code to get the job. However, he took 3h long lunches, came in late to work and apparently had a problem taking orders from women. At one point all the juniors got an earful because of his attitude and he got let go, not long after. It still saddens me because he could have made a really good career if wasn't for his attitude.
