At 90 seconds per resume, that would take up a full 8 hour day. Having gone through this myself, I don't think it's possible to do this much faster than that, even if you have an ATS that optimizes for that workflow.

I often found myself falling into patterns of poor judgement, e.g. mentally filtering out resumes based on the layout because, to my tired and bored mind, they looked similar to the resumes I had seen from unqualified candidates. I actually think some automation is helpful in evaluating them more rigorously.
