Also I couldn't stand being in the office for 8 hours, dressed up in clothes that I'd rather not wear. It was pretty stuffy. And most of the other interns were just too satisfied with wasting their times.
The allocated work could be completed in less than half of the time. Initially, I would ask my supervisor for more work, but I guess he got irritated, and instead of assigning more real work said go hang out with the other employees, and learn from them.
I initially tried talking to random employees, and try to figure out stuff to say, but after 5-7 minutes I'd run out of things to say, and go back to doing my own stuff.
