Pros

Competitive salary, good benefits, and snack bar

Cons

Constant re-org since 2025 and no communications about who was hired so they can come and go without being known. Old-school management team in Finance: Micromanagement and unsuitable manager who does not use positive reinforcement at all, instead challenge staff by nit-picking.
