Sure. I interned at Nortel for about a year. I was attending school while doing it, though. The internship really didn't leave me much time for school, so I got way behind in studies, homework and my grades were suffering. I also was splitting work time with school time, so my productivity at work always felt like I was cutting it short because I'd leave for school. So, for my type of work personality, it wasn't a great thing for me to be doing because I like to give 100% effort to 1 thing and not really split up my time with different things like school and work. Well, I guess I've been going to school and working ever since high school, but I feel like there's a difference between a part time job somewhere and a job at a large company like Nortel or something. I just recently turned down an internship opportunity at Bank of America doing some type of technology research/programming thing they came to me with. I've decided this time around I'm just going to focus entirely on school and wrap up this last year as solid as I can.
My advice would be this, if you're not doing much anyways and feel like you'd like to take a break from school then yea, go for the internship. An internship gives you relevent experience towards your resume and builds connections to people in the real business world. But, keep in mind that a lot of these places give internships because you say you're going to be completing schooll and getting a degree soon. So, the degree is really the higher priority.
