How to make interviews shorter and more focused

To shorten the interview without losing quality, don’t talk faster: arrive with prior evidence so you don’t spend the conversation covering what the report and the CV already show. If you know in advance where the candidate has solid signal and where to dig deeper, you define a few critical questions and reserve the time to go deep on them. The interview gets shorter because you remove the filler, not because you rush.

A long interview is rarely long because it needs to be. It’s usually long because it started without information: since you knew nothing about the candidate, you asked about everything, just in case. Half an hour goes to things the CV already said and to textbook questions that don’t inform. Shortening well isn’t about compressing; it’s about no longer improvising.

The filler has an origin: going in blind

When you arrive at the interview with nothing to look at, the conversation carries all the weight. You have to discover everything live, so you over-ask out of fear of leaving a gap. That fear is what stretches the interview.

Assessing before interviewing flips the order: much of the discovery has already happened. You arrive knowing how the person reasons in the role’s competencies, what looks solid and what’s still ambiguous. The interview stops being blind exploration and becomes focused verification.

Three moves to shorten it

1. Define two or three critical questions, not ten. Anchor on the competencies that truly matter for the role. The rest lengthens without adding.
2. Remove what’s already answered. What the report or the CV already make clear needs no question. Reserve the conversation to confirm and probe.
3. Go deep where you decide. Use the time you save on filler to truly follow up on the few things that matter.

The focus comes from prior evidence

The concrete method for knowing what to confirm and what to probe is in how to build questions from the assessment and in how to read an assessment report. The idea is simple: each signal in the report falls into “I already know this, I’ll confirm it with an example” or “I’m not clear on this, I’ll explore it.” Anything that doesn’t fit those two categories stays out of the interview.

That way the conversation time concentrates where it adds value, and the interview shortens on its own without you having to watch the clock.

When it matters most

• High volume. If you interview many people, a focused interview saves hours and maintains comparability. You filter earlier with prior assessment and interview in depth only those who show better signal.
• Tight hiring manager schedules. A well-prepared half-hour interview respects their time and still decides with backing.
• Multi-round processes. Shortening each round without losing focus makes the whole process more agile.

Mistakes when “shortening”

• Rushing the conversation. Talking fast isn’t focusing; it’s steamrolling. Focus comes from preparation, not speed.
• Cutting the follow-up. Follow-up questions are exactly what you should not cut: that’s where the depth is.
• Removing the common core. Cut the filler, not the questions that let you compare candidates.

In short

The interview gets long when you go in blind. Arrive with prior evidence, define two or three critical questions, remove what’s already answered, and use the time saved to go deep where you decide. Shorter doesn’t mean more superficial: it means without filler. To prepare that focus, review how to prepare the interview with evidence or the product.
