<p>is there more public speaking in computer science or business?</p>
<p>It depends on the job you get. Some software engineers and I/T people might give presentations to introduce their finished products to the client or educate the company on technology-related issues, but you can be a code monkey without much contact to other human beings if you prefer that. </p>
<p>Business is too broad of a field to answer your question. Are we talking about accounting, management, marketing?</p>
<p>What is “business”?</p>
<p>Not sure if this is what you are asking, but if you major in business (compared to other majors), you have more opportunities for public speaking and possibly will be required to do a lot more (e.g. class presentations, case competitions, case discussions).</p>
