It is really not that difficult.

1. For juniors, any sort of proof you have passion is enough. 2. Treat mid-levels as seniors. 3. Seniors have to show proof of passion (with longevity and intensity, AI and consultants exist for expertise and menial work) and competence (Take home problems with a long time scale with whatever tools they need. Use AI. I don't care, but be expected to be scrutinized for your design decisions, depth of exploration, and architectural write-ups.)
