For both the companies I interned at, had me sign non compete agreements. I had to agree that I would not work at a competing company for at least a year I was done interning with this company. This was not an issue for me since I had worked during the summer for both companies and I had a year break. But I do remember a co-worker who had gotten trouble because of this. This was when I was interning at Chemaid Laboratory. She has gotten a job offer at a competing company and took the offer. After Chemaid found out she was leaving for that company, they had actually sued her. She had been working here for many years so I guess she forgot that she signed a non compete agreement. I believe that was the reason she gotten sued.
