Pros
You can get a lot of responsibility quickly. Can move around easily within company. Good technology. Good co-workers (generally).
Cons
Cummins is an unfaithful employer. The ranking system with forced layoffs creates a poisonous atmosphere. Because of the system, employees doing good work are routinely fired. While the current company position is that there are nor forced layoffs, don't believe it. They will be back as soon as the current hiring binge is over. So be realistic - go to Cummins to get a lot of experience early in your career, then leave for a company that is more faithful to its employees. don't stay more than 3 to 5 years. You don't want to be stuck in Columbus mid-career when your turn to get fired rolls around. The hypocrisy between Cummins happy talk about a "great place to work" and the forced ranking and layoffs is breathtaking.
