Pros
They have a high starting pay and will promise you the moon to get you to leave companies and join them.
Cons
If they promise training, they are most likely lying. I was lured away from a company I was happy with based on a 30% pay raise and the promise of training for the BIM Coordination position. They job was put on hold4 months in and after 4 more months, they put me on "Leave Of Absence" whish is a non paid leave. They want you to hang around a few months in case they get work and can call you back in. They have a whole plan in place where they ambush you with the details the day they are putting you on leave. They have no concern for you as a person or for helping you to advance in your career. I should have done more research as there are 54 other reviews on here of people bringing up the constant lay offs.
