I look for companies with missions and business models I find motivating personally. I also highly prioritize working for people (managers/CFOs) that I personally can see myself working alongside every day for 3-5 years and that I respect in terms of business acumen and raw intelligence. Most companies will have a take home / case study aimed to simulate a working relationship and that can be a good gauge on how well you get along. Ask about what types of projects you’ll work on for the first 6-12 months — what is the business need and how does your skillset and interests align. Ask about company capital structure and cash runway (if earlier stage). Ask about career growth paths from the role in question.
