Pros

You gain a lot of experience in the power and gas markets.

Cons

No work/life balance. You will not gain the time lost back. CEO was rude. This is the team that will stay late because of others' laziness. Not worth it. Especially when you bring ideas that could alleviate some of that additional pressure... They'll try to sell it to you like you're doing something groundbreaking and important, but you're not. The leadership doesn't want to see you promoted because then they'd have to replace you which is almost impossible to do.

Pros

Management and coworkers are helpful, company has good structure, overall a good experience.

Cons

I've noticed that the company sometimes likes to save money on things that matter. Like maintenance that needs to be completed to prevent plant issues or buying quality tools for employees.
