Undergrad students no matter what major they are need to take advantage of CDSlink which NJIT offers. There are many internships posted on there. And once they apply, they should keep following up on the applications to the companies. When companies realize you are very interested, they will offer you a position. Another advise is you should be constantly networking all the time. Someone maybe have contacts to where you would like to work. One last advice would be do not worry about your GPA so much. Companies like someone who has experience in research or industry rather than someone who has high GPA.
