I agree it’s horrible to discriminate on personality types. As a counterpoint, though: in software jobs, the ability to pick up things fast is commercially valuable in some roles. As a hiring manager, if school grades helped me identify extremely smart folks who pick up things fast, then those grades are a useful tool. Not all jobs are the same, however, and so other hiring managers might set a lower bar for grades. But it’s important that we have these tools, in addition to the various other ways we evaluate candidates.
