Pros

Medical insurance for family, flexible working hours and career growth

Cons

Most days here are challenging due to difficult cross-team collaboration and noticeable knowledge gaps, which create an unhealthy environment for employees to learn, grow, and perform effectively. Management culture appears to be influenced by internal politics and favoritism, with inconsistent KPI evaluations affecting fairness in career progression and promotions. Employees are also given limited opportunities for skill development or external training, making growth and performance improvement difficult. Additionally, unclear responsibilities and job scopes often lead to miscommunication and unfair task delegation within teams. Overall, these issues should be addressed proactively by management and HR to create a healthier and more supportive workplace culture.
