Pros
The management is fairly young (30's-40's) and have a better understanding of what drives and motivates younger workers who are replacing retirees. Flex time, work from home are great perks for the modern young professional with a family and kids. The office culture is the most relaxed I've ever worked at. I'd rate cross-discipline communication at 4/5. Stantec is also a great place to climb up the ladder because it's such a large company with many opportunities. If you want to advance to a project manager from a biologist, they have internal training programs to train you in basic PM skills like finance, accounting, leadership. If you want to stay where you are and just rack up the experience in your field, you're free to do that too. Your team lead will check with you every quarter to see if you've achieved your career goals over the last few months. Management within my office location seems to strongly promote harmony. People don't need to step over others to advance and the general belief is that if the company takes care of it's employees, the profit will come naturally through more efficient and satisfied employees. The company is willing to fly you to other office locations just to meet and greet other Stantec employees in your field, so that you're not calling them and asking for information without ever knowing what they look like.
Cons
While the total number of people in a given department can be large among the company, like 50 wildlife biologists in the company, some departments can be pretty scattered resulting in only 1 or 2 people in an office location. It can make it difficult for the more isolated people to learn and advance.
