Any sales candidate could spend a solid day prepping themselves for any in-person interview and come across much stronger than they actually are. Unfortunately, this polished veneer is often good enough to land them on your payroll. The veneer is not peeled back until they have been with your company for a period of time.
Monster.com offers Interview Questions, Part 3 in their effort to assist candidates. I am not against a candidate preparing for an interview, but companies that over rely on the interview for screening end up with flashy veneer, no substance salespeople. We can’t preach this topic enough – it is far more reliable to run a hiring process with objectivity designed into a specific sequence.
Notice that monster even provides the candidates with a context and response structure?
