Full Time Interview - Best Prep Package

Hi everyone,

I am junior at a top 15 non-target and have a IB SA gig at a small regional boutique next summer. I want to try to make the jump to a BB (of course) and was wondering what prep course is the best for full-time interviews. I figure that I have to really understand my technicals come interview time if I am to have a chance and am willing to put in whatever work necessary. I heard the WSP Premium Package is the best at $424 but I want to hear what everyone else thinks.

Of course, I am going to have to network my butt off as well and I know that. Any recommendations on that would be helpful as well.

Thanks a ton.
