The overall culture of the company and how friendly and engaging employees are. As well as the willingness to provide an adequate learning environment. They were also were school schedule friendly and flexible with my work schedule and days I needed off.
What I wish was different
Increased local travel with project managers to active job sites.
This is a corporate professional environment, so be on time, dress appropriately, have a good attitude and you'll learn a lot and have a lot of great takeaways.
