Pros
If you want to work your way up in the company, there is much encouragement to do so. You can start at any position, come in with a good attitude, help train at new centers opening across the country (the company spread outside of Texas just last year, and is planning to grow many, many new centers over the next five years), become a floor supervisor, and eventually a manager. If you want it, you can make it. There are bi-annual reviews, yearly raise opportunities, employee parties and a "MyRewards" program that give you the opportunity to earn prizes and gift cards for doing a good job. Depending on the section of the building you work in (Games, Bowl, Cafe, etc.), the work can become monotonous, but your coworkers will be the reason you enjoy the job. For the most part, they tend to hire happy, well-balanced people that enjoy helping others have a good time, and they can become true, outside-of-work friends in the long run. The pay could be better, but it's competitive with other entry-level service-industry jobs (some departments more than others). It's also neigh-impossible to get fired, unless you put absolutely zero effort into it. And perhaps its cheesy, since people go to Main Event to have a good time (especially when family is visiting from out of town), having folks come up to you personally and say that they enjoyed their time and will be returning, or seeing those regulars come in week after week and recognize you for the good job you do, is just an all-around great feeling.
Cons
It comes with all the cons of the service industry--the work can be tedious and boring, the guests can be belligerent, it's either breakneck or incredibly slow, and sometimes the different departments don't see eye to eye. Multiple managers means multiple ways of doing tasks, and you have to keep tabs on which managers are working so that you know what things to prioritize. There is a HUGE focus on teamwork, and having even one coworker call in sick, not do their job or come with a poor attitude can create problems for MULTIPLE departments. Sometimes, the managers are quick to recognize faults and slow to recognize good deeds. And many, many times there is a lack of consistent accountability--one day, everyone can show up 10-15 minutes late and nothing is said, and the next one person can show up five minutes late and be written up. The job may not be fulfilling in the long run if you have no plans to move up.
