answer:It depends what type of company you’re interviewing with. Home mortgage branches of large banks usually are commission driven. Credit unions usually have no commission whatsoever. You’ll be staying an expert at what the current rates, policies, and laws are concerning mortgages, explaining lots of terms to customers, taking credit applications, and helping them decide which path is best for them. A lot of banks close with attorneys now but some still do their own closings, so you may handle that aspect also.
