Pros
Amazing company. I worked in the highway infrastructure division as a data collection technologist. The work is long and exhausting, you basically operate a collection vehicle that looks like a batmobile with all the digital recording technology during the summertime. You have to survey all the roads, so its 3 months of non-stop 7 days a week work (12 hours per day). It's really lax after that in the office for the rest of your time, you will get to work with Matlab and help process data. The 3 months of summer are long but you get to see the entire province which is really cool. The project Director, Ewing Kung is awesome. Miss that guy. Everyone else was great too. This will look amazing on a CV, and if you are great they will try to keep you. Great pay.
Cons
Long hours during the summer, maybe night shift. Sitting in a vehicle all day, ya it takes some getting used to. Sometimes stressful, especially if you are good enough to become in charge of the vehicle.
