Pros
I've enjoyed working for Langan since graduating a year ago. While I haven't been in the workforce long, I can tell that it is a progressive company (**comp time**) that really, really values talent. Being valued as an entry-level engineer has meant a lot to me. I have been to able to work on a number of complex projects, and, when deadlines aren't crazy, my superiors take time to teach. In other words, I do not always feel like a CAD monkey here! Keep in mind that, like your favorite chain restaurant, a particular office of a large company can be very different from another office in that same company. I have worked at offices other than my home office, helping out on different projects or because I was "taking a long weekend" to visit a city in which we just happen to have an office (remote desktops make such flexible management easy and productive). I saw the variety and have to say that I love working in a smaller, satellite office as I'm starting out. I feel comfortable approaching my supervisors for help, work regular hours most of the time, and still enjoy the big projects and high end software of a large company. Further, I will appreciate having the option to move to another city within the same company if my life ever takes me there!
Cons
Really valuing talent also has a drawback; managers take hiring too seriously/slowly, leaving the extra workload for other staff to pick up.
