My experience in graduate school is mostly about what knowledge, experiences and skills I should acquire to be prepared for an academic career. I have attended to many seminars related to my major, but, as most of the invited speakers are among faculty members, they all guide us in the same direction.  I think this mini-internship provides a great opportunity to learn more about the industrial jobs.  I am at my last year of PhD and I think this is a unique opportunity for me to have a sense of working in industry and this will help me to find where can I serve best, based on my interest and skills.
