What was your favorite class in undergrad?

When a company is interviewing you for an entry-level position, they're really trying to do their best to get to know you. If you've made it to the interview, they're already interested in hiring you. Now, their focus is on getting a feel for whether or not you're a good fit for the opening. When making their recommendation, a good interviewer will also be honest about whether or not the position is a good fit for the applicant's career goals and passions. If you're applying for a job with a niche engineering firm, hopefully your favorite class falls into that discipline.
