Pros

starting pay and the ability to work independently.

Cons

There is a significant amount of workplace drama and unprofessional behavior within the team, which can make the environment feel more like a high school setting than a professional workplace. Management appears to have limited understanding of employees' day-to-day responsibilities and is often resistant to feedback or process improvement suggestions. Employees may feel discouraged from raising concerns or proposing changes. Advancement opportunities also seem limited, with promotions and career growth often perceived as being influenced by personal relationships rather than merit. Additionally, the annual performance review process can be frustrating, as employees may feel that the scoring system makes it difficult to achieve the highest ratings and corresponding compensation increases, regardless of performance. Finally, there are concerns about workload distribution, with some leadership positions appearing to have fewer responsibilities than other team members.

Pros

Working as a team from different dept and function have been the best as colleagues were hardworking, hilarious and focused.

Cons

Low increment, bonus and benefit. Most of us felt the cost cutting and we accepted the situation. The higher management did not walk the talk and practice the cost cutting in their level.
