I made some educational games for McGraw-Hill Education - not a video game company mind you, but video game companies are not necessarily the only ones hiring people to make video games, keep that in mind all you job-searchers out there - and two games a week was not particularly abnormal. They were small games, mind you, each one focused around one particular educational lesson targeted towards a specific school grade, but still.
I will say this, I thought it would be pretty awesome to make games for a respected educational institution. I mean, I had creative control over the games, what they looked like, how they were made, etc. But in the end, it was not very fun at all because the overarching concept of each game is dictated. That was to be expected, I suppose, and it was fine in the beginning, but then it was just not fun anymore.
Working for a big game company I imagine would be somewhat similar. Unless you are the dude at the very top calling the shots, you are going to be implementing other people's stories, ideas, concepts, etc. For some people this might be fine, but for people who are looking to make their own video games, realize their own stories and visions, this is a very big compromise. However, it is fantastic experience that you can take with you whenever you go and start up your own independent studio or something, like so many people from the video game industry ultimately go and do. Most of the vets of the industry generally don't like working for big companies and much prefer working in small studios with a small core group of people.
At any rate, congratulations on the big interview! I hope it all goes well!
