      Pros

      The day I walked out the door.

      Cons

      Toxic, bullying leadership culture tolerated by the executive team. Regularly saw senior and junior colleagues in tears following meetings with senior executives. Focused on one thing only - profit. People don’t matter and concerns are swept under the carpet.

      Pros

      Excellent opportunities for independent work, allowing for deep-dive technical analysis and Python-based modeling without constant micromanagement. Great for self-starters who value flexibility.

      Cons

      Limited social interaction with the broader team due to the remote and specialized nature of the work.
