At the time I was at Merichem their business philosophy for the Process Technology Division (PTD) that I was in was to emphasize speed in our client deliverables. A process engineer like me would be responsible for developing the whole FEED package for a proposed caustic or amine treating system based on sales sketches and either Merichem, or more often than not, client specifications. Because of the emphasis on speed there were often late nights and sprints at the sales imposed deadlines that were a constant frustration; especially since the sales people were trying to dazzle the client with our speed rather than work with them to meet their deadlines. We would often break our necks to meet a "deadline" only to have the client wait several months to look at the product. This insane pace stressed many engineers enough to leave the company.
If you could adapt and manage the stress there were many opportunities to travel and interface with clients as a process engineer or you could travel even more as a tech service engineer supporting installed process units or as a sales engineer.
Benefits were OK. Compensation was average with usually a pretty good bonus.
