Just 4 short months ago when I was working for an engineering firm, I would attend “lunch and learns” one or two times a week. A company sales rep would bring in lunch and present their products to us engineers. Engineers are like college students and love “free” food, so we’d come out by the dozens to attend these “lunch and learns”. But the lunch wasn’t free. In exchange for lunch, we gave up an hour of our day to learn about the company’s products and potentially specify them on the projects we were working on.
