This is a great oil and gas company to "get your feet wet" but that development comes with a price. NOV pays around the 45th percentile of industry, meaning that if you're expecting compensation structures similar to that of the big O&G players, you're coming to the wrong place.
They operate in 3 distinctive business segments that all run autonomously. Autonomous is code for chaotic. There is a disconnect when it comes to company programs, processes and procedures, HSE compliance and rules... Beware.
I worked in a department that did not micro manage it's employees and that was the only thing that kept me coming back. I was able to get results and was left alone to work.
