Haha, well, hopefully nobody's opening with "Where do you see yourself in 5 years?" or any of the questions I listed! Doing either of those things is a great way to signal to the candidate that INTERVIEW MODE has been engaged. The goal isn't to remove noise, variance, and bias, but to control it in a way that produces a better assessment and a better experience for the candidate. This also allows the interview question + overall process to improve over time. Variance is present in every scientific experiment, after all, but the whole process of designing an experiment + evaluating the results is about controlling for known sources of variance and minimizing the ways unknown sources can get in. For example, one might frame the structured process thus: "We ask an identical series of questions to every candidate so we know everyone's getting a fair shake. It's important to us that we're evaluating candidates based on their actual experience and potential, not on their ability to do well in interviews. We hate tricky or ambiguous questions because they make the people we interview anxious and produce answers that are hard to evaluate fairly." You would want to do that before they came into the room, too, to control for the possibility that receiving that information in the interview room itself produced surprising interactions (more variance again). In general, the candidate should have a clear picture of what will be happening in an interview regardless, to control for the above as best as possible. (I can say from experience that if the above is done with a friendly demeanor and good bedside manner, the sense of relief in the candidate is palpable.) Imagine asking a candidate a question about a positive interaction with a previous manager that gets at the thing you're trying to evaluate. The candidate is naturally going to be happy talking about a positive experience! The framing of the question is intended to get them thinking about the moments you want them to be thinking about. "A couple of years" is not great because now it's a function of how the candidate perceives the phrase "a couple of years." More variance!What if one candidate specifies their impression of "a couple of years" and another doesn't? Asking the candidate to pick a time period explicitly also not great because now your impression is a function of the (time period, response) they chose and not just the response. More variance, again! It's better to ask questions structured in a way that gets at what you're really looking for. I don't know exactly what you're looking for, specifically — ambition, reasonable expectations around opportunities for and speed of promotion, alignment with company priorities, something else? — but there will almost certainly be questions that produce better diagnostic information and feel more natural to the candidate. Inherent in the interview process is the feeling that you, the candidate, want to give the answer that the person is looking for. "Where do you see yourself in (5/a couple/choose-your-time-period) years?" hits right at that anxiety (which is why a blog post like "what are they really asking?" is even necessary). Are you evaluating their ability to understand the question in the way you intended? If not, structure it in a way that reduces that possibility.
