<p>Dre, I think what he means by sales engineer is someone who sells engineering products and needs to understand the technology enough to be able to answer customers’ questions about it intelligently. In that case, he could really major in anything because all engineering firms sell something (whether it’s software, mechanical devices, services, etc). </p>
<p>The reason I ask why you want to be a sales engineer is because it’s really necessary to answer your question. If you want to do it because you want to have a lot of social interaction in your job, you certainly don’t need to go into sales - you could do industrial engineering which involves a lot of teamwork and interaction with all sorts of people in an organization, or you could major in any other area of engineering and look for a job with a company that involves more teamwork than others. If you really want to do sales specifically, then it would be a good idea instead to major in something broad like mechanical, chemical, biomedical, etc because technical expertise will be more important. In that case, industrial engineering probably wouldn’t be the way to go, since industrial engineers produce a lot more services than products.</p>
