Pros

- Solid pay and benefits - Dedicated and intelligent peers - You'll feel critically vital to the success of Calpine (until they say you aren't)

Cons

- Every day is stressful. I like a dynamic environment but I never knew if/when I was going to be considered hero or a zero based solely on the shifting sentiments of those above me. - It is a 24/7 job. You will wake up and check your email before getting out of bed, you'll check your email before going to bed, and you'll check it all day long. You have to because you will go from Hero to Zero if you miss anything - Frequent, small layoffs which are typically based on politics. - The review process is a joke. - Real promotions are rare. Sometimes people get shuffled but rarely does that cross organizational boundaries. In other words, career growth is limited.
