Pros
Large interesting company with good possibilities of career progression when times were good and oil prices were still high. A large variety of product lines to work with. Tasks are varied and often exciting. Friendly co-workers and managers (depends on the department). Average pay and benefits.
Cons
Poor synergy between the various departments within NOV. Some divisions do their own thing and do not carry others along. This sometimes make it difficult to deliver a complete suite of products and services to clients. This also led to some departments within NOV hiring externally recruits while other departments were laying off workers. As a result, many talented workers were laid off when they could easily have been transferred to other departments that needed their expertise.
