Hiring
Why every candidate should get the same first interview
ihiring team · Apr 22, 2025 · 2 min read
Most first-round calls are a conversation: a few warm-up questions, a walk through the résumé, and whatever the interviewer happens to be curious about that day. It feels natural, but it makes candidates very hard to compare.
The problem with improvised interviews
When each candidate gets different questions, you end up with different evidence for each of them. One person is asked about a hard technical decision, the next about their last job title, and the third spends half the call on small talk.
Notes written from memory after the call make it worse. Rapport, the time of day and the interviewer’s mood all find their way into the decision, even when nobody intends them to.
What structure actually means
A structured interview is not a script that is read out. It has a few fixed parts:
- A small set of topics tied to what the role really needs.
- The same core questions for every candidate.
- A clear idea, written down beforehand, of what a strong answer includes.
- Room for follow-up questions inside each topic.
Why it helps
Hiring research has long found that structured interviews predict job performance better than unstructured conversations. The reasons are practical:
- Candidates are compared on the same evidence, not on who got the easier questions.
- A decision is easier to explain, because it points to specific answers.
- First impressions have less room to take over.
- Everyone involved knows what a good answer looks like before the first call starts.
Structure is hard to keep at volume
Even a disciplined interviewer drifts after the twentieth call of the week. Questions get shortened, follow-ups get skipped and the last candidate gets a different interview from the first.
This is one reason ihiring runs the first round with SAM. The structure stays the same at two in the morning and two in the afternoon, for the first candidate and the five-hundredth.
Structured does not mean rigid
The best structured interviews still follow up. A vague answer should get a request for a specific example, and a strong answer should get a harder question. The structure decides what is covered. The follow-ups decide how deep each topic goes.
A place to start
You can apply this to your next role without changing any tools:
- Choose four to six topics that matter for the role.
- Write what a strong answer to each topic would include.
- Ask every candidate the same core questions in the same order.
- Review each candidate against the criteria you wrote, not against each other’s impressions.
