Check the GitHub repos of people who are on the team. Company code might be private but you can get a sense of who is on the team and how they code. Also see if you can talk to teammates before joining to get a sense of what the day to day is like. There are great engineering teams in the sense of eng practices but horrible culture in terms of management, getting along well with other orgs, etc. So you want to make sure you have both.
