Pros
The products that Cessna make is the top in the industry. Many talented people to gain valuable experience in all aspects. A good place to grow as a new graduate or for experience people. The culture is better than most aircraft manufactures. The employees are treated fairly. If you have an office job then your work life balance is better than you can hope for. Cessna is also a good place for non-ambitious individuals.
Cons
Cessna is now owned by Textron and there are some pros and cons. Majority of negativity towards Textron is due to the management and the direction Textron is heading toward. Cessna as its own entity is better off without Textron. If you are thinking about working for Cessna, be ready to be Textron Six Sigma certified which is a bad thing to me. Some people consider TSS a good thing but TSS is over used at Textron and now it is passing down to its subdivision ie. Cessna.
