Sure, having metrics on how often a company ships code, etc. would be helpful, but frankly I have about 10 companies on my list that I'd work for, and I doubt any of them would give you this data.
What I'd really like is not having to practice leet code problems for 3 months before I interview. The older I get, the less motivated I am to do this. I've worked in senior engineering roles at big tech (FANG) with 3+ years tenure. I don't think I managed to not be able to do my job and fooled people for that long.
I've interviewed people I KNOW could do the job, but they didn't get the optimal solution, or were nervous, or N things in the loop, and we ended up not hiring them. There must be some incentive to create a system that lowers these false negatives.
