I do understand that, but from my experience short coding tests give by far the best signal. We ran an experiment and found that actually not doing a pre interview and straight to code test gave us better results than interview then coding test. Why? Because people tend to hire people with qualities like themselves, and overlook many things. It also then caused people to overrate/underrate the analysis of coding tests based on the previous interview (as they (dis)liked the person). This also massively increased the diversity of our team.
