Some things I ask now since only OSS-friendly companies will link you to their repo:
- Ask how they get new devs set up and what Day 1 looks like.
- Ask how they go from feature to production.
- Ask what their coding standards are like. Many places implicitly inherit from more well-known standards because of the culture around a particular language and they may not mention that specifically -- drop hints and get them talking about it if that's the case.
Generally it's a pile of whatever if there's not much detail with their answers. But I'm probably falling into the same trap of interview-voodoo as hiring managers looking for leetcode scores or whatever.
