Vantaggi
In short, there are still a few smart, humble, passionate people at Crunchyroll/Ellation despite the turmoil at the company. Free lunch and dinner four days a week, a very nice office and opportunities to have a big impact on the anime industry.
Svantaggi
"Crunchyroll" is not a separate company. It's a product that the company Ellation maintains. The business teams for Crunchyroll are somewhat separated (though they're still in the same office) but engineering and many other departments are all part of Ellation proper. Read the Glassdoor reviews for Ellation. They don't bode very well. Petty politics and sabotage have resulted in layoffs for some of the most senior and well-respected engineers, as part of the company "growing" by buying up its outsourcing partner (whose CEO was conveniently ALSO the "interim CTO" of Ellation at the time). Now the rest of the senior engineers and lots of other people are leaving. There's a huge amount of distrust between ground-level employees and management.
