I just finished my sophomore year as an undergraduate at that point.
I was a integration testing intern. I did things like find bugs, write bug reports, write testing scenarios. I also did some load testing with jMeter. Another automated too they used at the time is called BadBoy. It could record and somewhat generalize testing. They had the whole process from starting an account, to communicating, to running through lessons automated in this way.
I can't remember why I needed to access the "real deal" production sql. I wouldn't have given it to me if I were the boss of me then.
They even let me work from home for a semester after working for them in the summer.
I was able to talk to anyone I wanted to. I remember making a spreadsheet to show that the scoring metric for ordering user suggested translations take into account the percentage of thumbs up and not just the difference between up and down. I showed the designer and it was in production three weeks later.
