However, I'm really regretting it at the moment.
I thought I'd at least have a say in how I approach problems, even if I didn't get to choose the problems I work on. Instead, I've literally been told, "Your job is not to do science. Your job is not think. Your job is to click a mouse. Do exactly what you're told in exactly the way you're told to do it. Now, stop asking questions and stop trying to think for yourself."
I realize that the people I'm working with have a _lot_ more experience than I do, but I do think there's value in considering alternate approaches to solving problems. A lot of the fault lies with me, too. In the case above, I didn't clearly communicate the business impact of what I was suggesting to my mentor. Either way, it's frustrating.
Most of it is finding the right team to be on. I still think I chose the right company, I just need to find a way to be on an R&D team. I'm under a 2 year contract, so I can't leave even if I did get frustrated enough to.
At any rate, know what you're getting yourself into. I did two internships on similar teams, but at different companies. Things are definitely done differently here.
There is certainly of lot of interesting work in industry, but it's very easy to wind up stuck doing menial repetitive tasks if you're not careful.
