      Business Outlook

      Pros

      Great hands-on engineering exposure with real projects that impact operations. Supportive team environment with knowledgeable engineers willing to mentor co-ops. Competitive pay for a co-op role and valuable experience in a large manufacturing setting. Good emphasis on safety and process discipline.

      Cons

      Some projects can move slowly due to corporate processes and approvals. Limited flexibility in work hours during peak production periods. As a co-op, long-term project ownership can be limited by rotation length.
