Mark Herschberg has tracked criminals and terrorists on the dark web and created marketplaces and new authentication systems. With a long career as a CTO, he has launched and developed new ventures at startups and Fortune 500s. But one thing Mark realized along the way is that success doesn't just lie in being to find the right answer; it lies in being able to communicate it to others. His journey to master emotional intelligence in the workplace led him to help start MIT's "career success accelerator," the Undergraduate Practice Opportunities Program, where he teaches annually. In his book The Career Toolkit, Mark shares ten chapters that deliver the essential skills no one ever teaches you. From how to nurture relationships both inside and outside your company to successful negotiation and job interviews, Mark's lessons arm readers with top skills, professional advice, and an understanding of the modern workplace's— often overlooked— interpersonal dynamics— everything you need to be successful in your career.
