Pros
Invenergy is obviously an industry leader that is working on exciting projects in a fun & high paced industry with a global footprint. Headcount and departments are getting very large which means many job opportunities and the ability to interact and learn from many smart people.
Cons
Ultimately, there is a tight knit "boy's club" of upper management where all of the real authority and leadership power reside. These individuals rarely offer insights into why certain decisions are made and it's clear that they have no intent of sharing their responsibility with subordinates. If you make the right friends in the right group, there is an opportunity for upward mobility but the title changes are virtually meaningless in terms of actually being given more responsibility, and the compensation levels and adjustments constantly lag the market. Return to office policy is extremely draconian with badge scanning systems used to track and chastise their adult employees.
