"Even 4x2 hour interviews is still only the equivalent of a single workday."

So about $400 of labor?

Neither the prospective employee or employer get a good 'feel' of each other because both are giving 'performances' in a completely different context than actual work.

No one has any real, statistically valid and logically sound, data on hiring practices. It's all dogma & "intuition".
