Pros
From the outside, the company looks great. Inside, it's another story. Lots to do as the company developed so quickly in the last 15 years so if you are resilient and a hard worker, there is a lot of successes to garner. If you have the right bosses, you will get great recognition, visibility and opportunities. Very good salaries and benefits.
Cons
Company has been there for over 50 years and started with TV cable only. So there is a big number of people who have been there for 20+ years, who are very old school. What defines expertise is knowledge about the organisation and internal processes. And internal acronyms ... In my book, expertise is business acumen, how you can think outside of the box to do things differently and better. So be ready to face stubborn and old-school people. On some instances, it's a whole department.
