How do you evaluate a startup company when you are applying for a job?

I'm considering joining a Series A startup, and I want to do a comprehensive due diligence before making the leap. What key factors should I dig into during my evaluation?

Funding/Financials, Product/Market Fit, Team Dynamics, Tech, Growth Potential

Is there anything else I'm missing? Where can I do further research on the company?

What’s the runway versus the burn rate? Who are the founders and who are the investors?
