Pros
ADT is certainly the brand leader for security in the US, and that helps with sales. The commissions are good, and I think that this prepared me well for future sales jobs. While I was at ADT, new employee training improved and new hires are taught about the product and service instead of just how to close a sale.
Cons
From the job description/interview/hiring process, I understood that my job would be easier: sales by appointment, lots of leads for outbound calling, etc. I was deceived. In reality, sales reps do door-to-door sales in horrible weather and often get the door slammed on our faces. Good leads are given to manager's favorites, and many sales reps end up doing cold calls. Sales commissions are good, but you have to use scare tactics to close the sale and meet the sales quotas and goals.
