The resume workshop was helpful in fine-tuning my existing resume. They suggested a few visual things like removing the photo of myself, elaborating on some of my achievements, adding dates, and widening the margins. They also suggested that I remove the references section and some older jobs so that I can keep the whole thing on one page.
As far as interviews, the most helpful advice for me was to ask about company culture/expectations in order to learn more about the environment. These suggestions are better than technical advice about how to answer programming questions.
