It's easy to forget that someone might have once held the position you're applying for -- or, more importantly, that the role might have evolved since it came on your radar. Don't be afraid to ask HR what this job looked like before you were interested in it. This can include what the responsibilities looked like, how many other people currently hold this position at the company, and even where HR thinks it's going in the future.

Getting HR's perspective on the history of your potential role can give you unbiased insight into your department, and let HR know that you're interested in your future at the company -- not just your present.
