Pros

Calpine is a great start of a career. As CIS analyst, a prospect candidate can acquire in-depth knowledge of power trading and power markets.

Cons

Noise, stress, imbalance between personal life and work. Frequent workflow interruptions. It feels as mid-executive management fails to retain quality personnel.
