Pros

Good pay, PTO requests almost always accepted, nicer people work in offices outside of NY

Cliques are rampant, toxic managers, you're only recognized if you give your nights, weekends, and time off to this company.

Pros

Talented and supportive colleagues in many teams Opportunities to work on interesting projects Some flexibility in work arrangements

Cons

The company regularly lays off qualified employees, sometimes in large groups, with little warning, often favoring cost savings over performance or contribution. Management is not transparent—line managers often cannot explain strategic decisions, and upper management rarely shares the financial situation or reasoning behind layoffs. Terminations can happen via a single call with minimal support or explanation, which is demoralizing and stressful for employees. Career growth and job security are unpredictable due to frequent restructuring.
