Ventajas
Work can be interesting and enjoyable. Fellow employees are (mostly) good to work with and supportive, even across disciplines. 9/80 work schedules. Entry level positions can advance fairly quickly if you do the work.
Desventajas
Need to watch your currency in your degree specialty. Many jobs are much more systems level, and any tech edge you might have going in may be lost after a few years in that sort of job. Work/life balance is not a priority, even in long-term "push" activities. Push can follow push, ad infinitum. Review (and therefore lay-off list) ratings are REQUIRED to be distributed across program and down to team level, regardless of actual team (or individual) performance. Even high performing teams must have a (or more depending on teams size) "basic contributor", even though that person might be much better than a high performer on another team. Higher level jobs require changing jobs - you have to leave your team in order to be promoted. Entry level management tasks (at Aeronautics Fort Worth) do not align with corporate training for those managers. For example, corporate work load at Manager level says 20 hours tasks, 20 hours people. Actual is more like 40+ tasks, and then deal with your employees.
