Pros
The brand itself has an allure, one of the few original studios with an immense history in film, which does look good on a resume (we'll see how long that lasts). Getting to work on some of the content is also a wonderful experience.
Cons
Previously, Warner Bros. was a great company to work for, but from the minute David Zaslav took over the company has become a dumpster fire. Cuts are often, with little understanding of what departments are working on and what the roles being cut do. Everyone, from the top down, lives in fear as to who is next on the chopping block. If you are one of the "lucky" ones that aren't cut, it simply means that your workload will quadruple, but don't worry, they will be another round of layoffs just a few months later, so any relief you might feel in the immediate will be gone soon enough. If you are looking for a stable work environment where your work is appreciated, this ain't it. I wouldn't recommend this company to my worst enemy.
