The workload at a big four is not light as you will be working late many weekdays and possibly weekends. You will really develop some time management and prioritization skills due to this type of schedule since your peers will be putting in the same hours you are, if not more. Just spending that amount of time with my coworkers really helped create a camaraderie between our team and despite how tough some days were, you can tell management cares about everyone's development.
Many resources, great connections within company
Rough work days, late nights
