Engineering exam questions can be found online through resources like MIT's OpenCourseWare, which offers a variety of tests across different subjects. A general search on Google also yields numerous sample questions, both solved and unsolved. The discussion includes a query about solving a specific equation involving a sum series, particularly when the number of additions becomes large. A suggestion is made to find a closed expression for the sum of e^k from 0 or 1 to n and then equate it to the known sum to solve for n. Overall, the conversation emphasizes the availability of resources for engineering exam questions and methods for tackling complex equations.
