You may go ahead and attend the interview through the college, but do mention your previous interview with the company before attending or during the interview. They may either ask you to attend again or ask you to leave. Do not neglect the chance because if you performed well in your previous interview, you will have a double chance. If you haven't performed well before, you may have another opportunity. All you have to do is mention this when you attend the interview.
Wish you all the best.
