Pros

Management lacks clear direction. Roles and responsibilities are poorly defined, which leads to confusion and inefficiency. You often end up working on tasks that have little relevance to your actual role or professional development. There is virtually no investment in employee growth — no structured development plans, no meaningful feedback, and no encouragement to build new skills. The culture is toxic. Cliques dominate the workplace, and collaboration across teams is minimal. When things go wrong, the default response is to assign blame rather than find solutions. This creates an environment where people protect themselves instead of working together. Over time, it becomes stagnant and demoralizing.

Cons

The technical work itself can be interesting, and the company operates in a relevant industry with potential.
