      Solid work-life balance, but slow decision-making

      Software engineer (swe ii)
      Recommend
      CEO approval
      Business Outlook

      Pros

      Good work-life balance compared to many consulting companies. Stable environment and structured processes.

      Cons

      Decision-making can be slow due to large corporate structure. Salary growth may feel slower than at startups or U.S.-based tech companies.
