Pros

- Decent salary - Flexible working hours - Employees are trusted in

Cons

Lack of management and planning: - Nothing gets done unless it’s almost too late, panic and overtime hours before deadlines because no one makes plans or gives information. - Employees are blamed for unrelated problems, for example technical problems or someone being sick - Very low budget for appliances, broken tools don’t get replaced, computers are ancient - Old facilities with no maintenance: water damage, dust everywhere, loud noise level - Management doesn’t listen to employees (who often know their stuff) opinions or it takes forever to actually do something about them Overall very unprofessional environment for a high tech company!

Pros

I am truly grateful to have crossed paths with many of my colleagues, who I found to be very smart and capable. Benefits are decent, and they have an on-site cafeteria.

Cons

Low salaries, poor raises, very limited opportunities for advancement, and an incredibly dysfunctional, toxic work environment. The current site leadership here is incredibly unprofessional, and can be openly hostile to any employees who fail to properly "kiss the ring". Staffing is lean, most departments are chronically understaffed, and experience abnormally high turnover. Advancement is possible, but it requires a complete lack of work/life balance, and the lack of any meaningful raises means you'll be making less than new hires by the time you actually get promoted. HR is absolutely atrocious, and actively enables a culture of retaliation. Middle management is largely composed of incompetent yes-people. High performers people are regularly thrown under the bus and let go in order to pass blame downwards, I've seen many talented people get go for incredibly petty/retaliatory reasons by their ineffectual bosses to prevent themselves from getting fired. As a result, many departments are locked into a perpetual cycle of trying to shift blame onto one another, resulting in a debilitating amount of infighting; a direct reflection of the poor leadership of the organization. Upper management is incredibly top-heavy, and entirely detached from the day to day operations of the organization. Outside of a continuous push for monthly, quarterly, and annual revenue to appease shareholders, little to no effort is made to resolve in day to day problems faced by employees. Higher level positions are almost always external hires. Numerous desperately needed positions are regularly unfilled/get withdrawn due to lack of budget allocation from upper management.
