Pros
Nestlé is the leading consumer goods company in the world, showing an incredible stability and continuity in its performance and growth. It probably has the most international and multicultural environment of any company. If you are looking for a job where you can experience working and interacting daily with people from completely different backgrounds and cultures, and if you love traveling (short term trips / projects or long term relocation), Nestlé is definitely a company you should consider. Internal mobility in terms of function, location, product category is great, which means that you can always find a new challenging job within the company. This is probably a reason why Nestlé has one of the highest tenures.
Cons
Due to its huge size the company can at times be perceived as slow and bureaucratic. Most jobs at Nestlé require frequent travel or relocation, which is not always appreciated by everyone. The environment is not as meritocratic as in some of the American consumer goods companies and promotions are often linked to seniority or years of service. Top and middle management positions are almost always filled with internal people who have worked for the company for several years.
