Unsupportive and unresponsive leads and managers, training targets that are always on the move and therefore never mean anything once complete, no yearly bonus or perks for new employees (analyst level), impossible to get work that actually aligns with your abilities, a review process where you just review yourself, talented people excluded from promotion or advancement because they didn't volunteer their weekends on behalf of the company that year, and in general you can expect to be treated as disposable labor on the project you are assigned. The list goes on. Good luck finding a reference when you try to leave. Avoid at all costs.
