      Great coffee but questionable leadership and integrity

      Anonymous employee
      Recommend
      CEO approval
      Business outlook

      Pros

      Great coffee machine, which you will need.

      Cons

      The company is run on recent college grads and ChatGPT. Seriously. CEO lacks integrity and character. Don't believe what you're told, get it in writing.

      Inconsistent policies and lack of transparency

      Special security technician
      Recommend
      CEO approval
      Business outlook

      Pros

      Gained experience working in a security-focused environment with exposure to classified processes and coordination across teams. Some coworkers were professional and knowledgeable, and the role provided opportunities to develop skills related to access control, compliance, and security operations

      Cons

      Policies were applied inconsistently among employees, particularly regarding telework and workplace expectations. Communication from management lacked clarity and transparency, especially around key decisions affecting employees. Concerns raised through proper channels were not addressed in a timely or meaningful way. Overall, the work environment felt uneven in how employees were treated.
