They are often big companies to work for. Some of these companies are so consistent with their annual revenues that they understand that their workforce is the key to their success. Many of the 500 best companies on the Fortune list are included in CNN Money's list of the 100 best companies to work for. That said, you can learn a lot of really good things in a company like that.
It was my first 3.5 years of employment. I learned a lot about good documentation and a good process. I networked with many people and organizations and also learned from them (this is how I got my current job). Usually, I see that the smartest and best students in my school and program go to companies of those well-known brands, namely Boeing, Lockheed Martin, GE, Northrop Grumman, Raytheon, and they seem very, very happy in their jobs there.
Every year, Fortune partners with the Great Place to Work Institute to survey employees from hundreds of top companies in the United States to determine which companies will be named as one of the 100 best companies to work for. It depends on the company, at the beginning of doing an internship, my Fortune 500 company has a very structured development plan with a lot of training, while the other smaller company I worked for had no structure and was simply entrusted with projects to be carried out as a mechanical development engineer as part of a team. I have found that companies on the Fortune 500 list or similar are terrible at developing resources (you) (training and offering a challenging and attractive job), they are usually the first to reduce employment benefits in difficult times and to offer few opportunities for promotion. Personally, I've learned more marketable skills while working in smaller companies than larger ones.
In addition, companies provide organizational data such as size, location, industry, demographics, functions and levels. Then, the analysis of the survey data and the test evaluation results are taken into account in a combined score to compare and rank companies that create a more consistent positive experience for all employees.
