Some times I'll come across a job posting that requires you answer a few questions in your cover letter. The questions are usually what a person in that position would typically be asked in their jobs.
For example, suppose a company has a job posting for client support, the post might contain the following hypothetical question:
A potential client wants to request a demo and available monthly packages. You know that the company packages were recently updated, but you can't recall the details, what do you do?
The company wants to see how a potential candidate would react to being asked a question they didn't know. Would it be unethical to contact a customer service rep and ask those same questions?
