Competent and interviews well can be disjoint sets. I've worked with lots of people from FAANG and helped many of them level up. There are psychological suggestibility and willingness to be slavish to your career heuristics that can silently filter.

These days I ask if they're open to a four day work week as a proxy for their stance towards the data supporting associated productivity and work life balance optimizations. Smart managers exist and this has been an excellent filter mechanism in their interviews for my attention.
