Pros

Compensation is well for the job duties. There is a sense of comradery in the office. Hybrid work style, 3 days in office and 2 from home. Flexible working environment..

Cons

On the IT side of things, no one really knows how to manage. In place promotions make sure that technical people become managers whether they have the skills or not.
