Pros

One of the best reasons I enjoy working at Calpine are the people. We have the best and the brightest this industry has to offer. The compensation is great and the benefits are second to none. We have a management team that gets it and continues to move the company to higher heights.

Cons

As with any company there are always areas of improvement but I don't have any that I would highlight as being a showstopper.

Pros

- Hybrid schedule (3 days in office, 2 days remote) with a generally low-stress environment and good work-life balance. - Stable work environment with predictable expectations and manageable day-to-day responsibilities (specific to my team/manager) - Free catered breakfast on in-office days and a well-stocked kitchen. - Competitive annual bonus program, including prorated eligibility for employees who join mid-year. - My manager lets employees manage their workload without excessive oversight. Management experience may vary across teams.

Cons

- Lack of team culture and camaraderie. Interactions are only work-focused, with little to none team-building or company-wide events. - Compensation is below industry standards for similar roles. - Limited opportunities for career growth, skill development, and innovation. New projects are infrequent, and work can become repetitive and mundane over time. - The Business/Data Analyst role is heavily focused on QA/testing and may not align with expectations of a traditional analyst position. - Workload is highly inconsistent, ranging from very light some days/weeks to exceptionally heavy. - Many IT roles are contract-to-hire, with full-time conversion timelines that can extend well beyond expectations and lack clear communication. - Employee feedback/criticism is not well received by upper management.
