Pros
This job will have you working with other individuals who are mostly gamers and intellectuals (read: geeks), and the competition is extremely high for promotions. If you are able to multi-task, and can handle multiple chat-based conversations at once, and can organize an insane influx of new information, while navigating the web and emails quickly to provide accurate information with an over-friendly tone, this job is for you. The benefits are very good, and there are yearly Christmas bonuses, and profit sharing. The office environment is very geek friendly, with lots of Blizzard decorations, toys, etc... one of the core values is "embrace your inner geek," and you are encouraged to be someone who can relate with World of Warcraft customers. The environment is a place for gamers, and it's recommended that you have a strong passion for Blizzard products (which really isn't that hard.) ;)
Cons
The availability of training and the fairness of management evaluating eligibility for promotion has increased greatly over the years... however, if you are not maintaining your rank in the top 25% and constantly actively seeking to better yourself, you may not have job security, as seen recently with a large percentage of layoffs due to apparent sales /subscription shortages. This job requires a high level of self-motivation and self-management to stay focused and on-task to maintain your productivity and positive attitude when faced with customers who often have un-educated and unrealistic expectations.
