* You're given opportunity to gain valuable skills, but your compensation will not rise accordingly. Base pay does not really change beyond promotions, with yearly raises being <2% which will not keep up with inflation. You are expected to be on call for week-long 24/7 shifts fairly regularly and respond within 10 minutes to any pages, which I found to be a pretty big detriment to my personal life (all without additional compensation). Expect to do live monitoring on weekends and evenings for big sports events, also unpaid. Once you have experience, it's pretty easy to find a better paying job with fewer oncall expectations outside of DraftKings.
* Product sets deadlines before technical planning is done, meaning engineers are frequently having to step up and be 'heroes' to get features out in time. This leads to a lot of tech debt and production bugs, which further worsens on call for engineers.
* DraftKings is increasingly shifting to metrics to measure engineer success, meaning the number of 'points' of tickets you do will be compared against your peers. Managers do not take into account whether you were on vacation or your contributions towards helping your teammates get their tickets across the board.
* Can be a bit of a boy's club. My immediate team was always welcoming but women engineers who have to collaborate with other teams are often patronized or dismissed. Expect to repeat yourself a few times if you're a woman who has to talk to one of the all-male engineering teams.
* Senior management seems lacking -- mostly they seem to ignore employee feedback and always show up right before product launches to demand changes that should have been suggested much earlier in the planning process (demanding that features previously agreed to be non-mvp get added last minute pre-launch, changing the product name/color scheme).
