Pros
HP has a rich history and The HP Way is the driver of culture - collaboration, teamwork, growth, ownership, responsibility, and recognition - very like the Golden Rule. The people are bright, competitive, supportive, and (like family) they care about customers and colleagues. Collaboration is amazing. Salary and benefits are great. The opportunities for growth in just about ANY area or part of the world is amazing. You are encouraged to learn, take calculated risks, and to fail fast. This is a very ethical company.
Cons
Computer Technology is a fiercely competitive field where every penny matters and the landscape is constantly changing. Working for a Fortune 100 company is a double-edge sword and you are only as good as your last contribution. Always a LOT of change, not only technologically, but also organizationally. If you aren't an agile, flexible person - this isn't your company. Expect long hours and hard work to come with your good salary and benefits.
