It was best described when someone said it was like a technology factory with little monkeys (college grads and Northeastern co-ops) on the factory line. I wanted a job in marketing and while the title "Product Marketing Specialist" sounds like marketing...trust me it's not. I sat there along with all the other monkeys for a whole year entering product descriptions until I was numb. I also answered phones for a few months. The work was so un-stimulating and un-challenging I felt like I wasn't doing anything with my brain; and it was especially hard since I'd had jobs before hand where I felt really valued and used my brain all day while continually being challenged. This was the complete opposite. I was so under-valued and not challenged in the least. I was so replaceable that it wouldn't matter if I were sitting there or a dummy in my place who could type. Really, it was that bad. Some days I would go in there crying.
I also tried to move to a different dept at some points, desperate to change my boring routine. For some it worked fine; but I worked my butt off for months and was never moved. However, some employees who had just joined the company were promoted right away. This was very difficult for me. I couldn't get out of that company fast enough. One year felt like an eternity.
