I think it is much harder to prove age discrimination earlier in the hiring the process. E.g. when screening resumes. How would you find out the real reason when a particular resume fails screening? Thus the likely incentive for the company is to avoid older people as early as possible. This means older good candidates would fail screening more likely: in effect, discrimination. It's so often forgotten that the intent of the law vs its actual effect could be in conflict.
