2. Where do you see the $(team you're interviewing for) in 2 years? - do they respect the team or are they looked at as an annoying expense? - do they talk about training opportunities, growth, etc?
3. What is your favorite aspect of working here? - If it's a stock bullshit answer, I dig more. - If they duck it, that's a smell. - If they answer honestly, then that's a really valuable datapoint.
4. Every company is carrying some amount of technical debt -- what's the tech debt situation here? - how much they think there is - what they're doing about it
5. How would you describe the culture and if/how it is maintained?
5a. Is there an active mentoring strategy? What does that look like?
