- 1.0Danger, Danger, Don't HireSoftware Developer • Current EmployeeNew York, New York, United StatesNovember 16, 2025Pros: Anyone who has to bring their Chief of Staff from one organization to the next, in the same exact role, is someone who doesn’t value diversity of thought. Danger, danger, danger. Run, don’t walk.Cons: I have no more cons.
- 1.0Getting significantly worseSoftware Developer • Former EmployeeNew York, New York, United StatesJune 5, 2024Pros: Good deal on working from home vs. office.Cons: Terrible culture. Bad publicity almost every day. Partners disagree and don't speak with each other, causing harm to the company. Some rogue researcher hacked into a poorly managed software setup, got paid over $20 million, and caused a major regulatory and internal backlash. People around are afraid that the SEC will shut down the company for gross negligence and mismanagement.
