I believe there's nothing wrong with coming up with biases based on evaluating a person's technical abilities for a job role. (Isn't that the whole point?) You know the part where the requirements mention a skill set you should possess. If a person with a particular skill set/course wasn't able to perform as expected, then maybe that is not what you want. However, IMHO, it becomes discriminatory when you base all of your arguments off of one data point. A class can be made up of a lot of different type of people with differing views on how to solve problems etc. When I start to drift away in such situations, I tend to look for more data points. A deeper analysis into what culmination of factors might have caused this, can really solve this. Or so I believe. And to be fair, you did hire the other person with the same course. So, maybe it is a fit. Just that the other person may have lacked other abilities/skill set to perform the job properly.
