Burnout Culture - You will easily find a lot of staff signing on at 7am and working to 10pm daily (weekends included),
Micromanagement - Too much to list, but one of note is that there is a Slack channel dedicated for notifying everyone when you are away from keyboard.
Benefits - No company contribution for spouses/children medical/dental. Expect to pay high costs for doctor visits. No 401K match. 10 vacation days per year (and you will be asked if plan on working on your days off).
Bonuses - What you sign up for is not what materializes.
Tech - Brittle and unstable.
