The difference between hiring an exceptional talent and merely filling a position often comes down to how well you conduct your interviews. The way you handle interviews can make or break that process. So, if you’re a founder or hiring manager, it’s time to rethink your approach.
Why Your Interview Prep Matters More Than You Think
Most people focus on whether candidates are prepared, but here’s the kicker: interviewers play just as big a role in making (or breaking) the hiring process. In fact, a study by Aptitude Research found that 82% of recruiters lose candidates due to a poor interview experience. That includes inconsistent communication, unprepared interviewers, and a lack of structure.
Want to avoid that? Let’s talk about what you can do differently.
Before the Interview: Laying the Groundwork
A solid interview starts long before you meet a candidate. Rushing into interviews without preparation leads to wasted time, bad hires, and frustrated candidates. Here’s how to set yourself up for success.
1. Get Clear on What You Actually Need
Before you start filling up your calendar with interviews, make sure everyone on your team is on the same page about what you’re looking for. Ask yourself:
- What are the key responsibilities and deliverables for this role?
- Which skills are absolute must-haves, and which are just nice bonuses?
- How does this position contribute to your company’s long-term goals?
- What kind of personality and work style will mesh well with your team?
Having clear answers prevents last-minute confusion and ensures you’re evaluating candidates based on the right criteria.
2. Build a Structured Interview Process
A structured interview is not about making things robotic. It is about being fair, consistent, and making better hiring decisions. Here’s how to do it:
- Ask role-specific questions that dig into real-world experience. Generic questions like “What’s your biggest weakness?” won’t tell you much. Instead, focus on scenarios directly related to your startup’s challenges.
- Use behavioral questions to see how candidates have handled past situations. If the role requires adaptability, ask about a time they had to pivot quickly.
- Include practical assessments to test skills in action. This could be a coding challenge, a case study, or a mock sales pitch, depending on what best fits the role.
- Establish a scoring system to compare candidates objectively. Set clear criteria for what makes an answer strong, decent, or weak.
- Use a decision matrix so every interviewer rates candidates based on the same benchmarks. This helps remove bias and ensures you’re hiring based on merit, not just gut feeling.
3. Get Your Interview Team Ready
If multiple people are involved in the hiring process, make sure they’re aligned before the interviews begin. That means:
- Assigning each interviewer a specific focus area (technical skills, culture fit, leadership potential, etc.)
- Ensuring everyone has reviewed the candidate’s resume, portfolio, or past work
- Coordinating questions so candidates aren’t answering the same thing multiple times
- Training interviewers on what not to ask to avoid legal issues
A well-prepared team creates a smoother and more professional interview process, leaving candidates with a great impression of your startup, regardless of whether they get the job.
During the Interview: Execution Strategies
Once the interview begins, your job is not just to ask questions. It is to create an environment where candidates can showcase their true capabilities. A well-run interview feels more like a conversation than an interrogation. Here’s how to make it count.
1. Set the Tone with a Strong Opening
The first few minutes can make or break the conversation. A nervous candidate won’t give you their best answers, so help them feel comfortable right away. Try this approach:
- Give a quick but engaging intro about your company. Skip the generic pitch and share a compelling story about why the company exists.
- Explain your personal connection to the mission. People relate to people, not job descriptions.
- Lay out the interview structure so they know what to expect. This removes unnecessary anxiety.
- Ask if they have any initial questions. Giving candidates a chance to talk early can ease nerves and set up a more natural conversation.
When candidates feel at ease, they’re more likely to give honest, thoughtful answers instead of rehearsed responses.
2. Ask Open-Ended, Layered Questions
Surface-level questions lead to surface-level answers. Instead of asking if someone has experience, ask them to walk you through how they handled something.
- Instead of: “Have you managed a team before?”
- Ask: “Tell me about a time you had to rally a team through a tough challenge. What was your approach, and how did you measure success?”
To get deeper insights, use the What, How, Why method:
- What did you do? (Describe the situation)
- How did you approach it? (Explain the process)
- Why did you do it that way? (Share the reasoning)
This structure helps you see not just what someone did, but how they think through problems.
3. Listen More Than You Talk
Interviews are not about proving how great your company is; they are about understanding the candidate. Follow the 70/30 rule: listen 70% of the time, talk 30%.
While they’re speaking:
- Take meaningful notes. Don’t rely on memory.
- Look for patterns in their responses. Do they take credit for successes but blame others for failures?
- Pay attention to both what they say and how they say it. Confidence, hesitation, and enthusiasm all reveal something.
- Observe body language and engagement. A lack of eye contact or vague answers can be red flags.
If a candidate gives a vague or overly polished answer, dig deeper:
- “That sounds like a great result. What specific steps did you take to get there?”
- “You mentioned a challenge. What would you do differently next time?”
4. Look for a Growth Mindset
Startups move fast. You need people who can learn and adapt quickly. To gauge learning velocity, ask about:
- Their biggest professional learning moments
- How they’ve adapted after past failures
- Their approach to developing new skills
- A recent challenge that forced them to level up
If they struggle to talk about failure or personal growth, that’s a red flag. The best candidates are reflective and can clearly articulate how they’ve evolved.
After the Interview: Effective Evaluation
So, the interview is done. Now what? The post-interview phase is where good hiring decisions are made (or messed up). Relying on gut feelings alone can lead to bad hires and costly turnover. Instead, take a structured approach to evaluating candidates.
1. Capture Your Thoughts While They’re Fresh
It’s easy to forget key details once you’ve interviewed multiple candidates, so write down your impressions right after the conversation. Use a structured feedback form to keep things objective. A solid form should:
- Separate facts from gut feelings – Did the candidate provide strong examples, or did they just sound confident?
- Map feedback to predefined criteria – Score them on skills, experience, and culture fit based on what you decided before the interview.
- Include specific examples – “Strong communicator” is vague. Instead, write: “Gave a clear, step-by-step example of how they handled a difficult client situation.”
- End with a clear decision – Would you hire them? Yes, no, or maybe (with conditions)?
This structure ensures you’re evaluating candidates fairly rather than making decisions based on personal biases or small talk.
2. Align Your Hiring Team
If multiple people interviewed the candidate, don’t rush to a decision individually. Instead, hold a calibration session where interviewers:
- Share their observations and examples from the interview
- Challenge assumptions and call out potential biases
- Reconcile different opinions (one bad answer shouldn’t disqualify an otherwise strong candidate)
- Make a collective decision based on evidence, not gut feelings
These sessions help prevent situations where one interviewer loves a candidate while another dislikes them for unclear reasons. Focus on what was actually said and done, not just personal impressions.
3. Continuously Improve Your Hiring Process
Every hire (or miss) is a learning opportunity. Track key metrics to refine your interview process over time:
- Offer acceptance rates – Are great candidates choosing other companies?
- New hire performance – How well are hires performing after 3, 6, and 12 months?
- Interview-to-hire ratio – Are you interviewing too many people for too few hires?
- Diversity metrics – Is your process unintentionally filtering out certain groups?
If you’re seeing low acceptance rates, candidates might be unimpressed with the process or the way your company is presented. If new hires underperform, you might not be assessing the right skills. Use data, not assumptions, to adjust your approach.
Avoid These Common Interviewer Mistakes
Even the best hiring managers can fall into certain traps when evaluating candidates. The key is being aware of these biases so you can make hiring decisions based on facts, not just gut feelings.
1. The Halo Effect
Ever been wowed by a candidate’s Ivy League degree or impressive job title? That’s the Halo Effect, where one standout trait overshadows everything else. The problem? A fancy degree doesn’t always mean they’re the best fit.
How to avoid it:
- Use a structured scoring system with multiple evaluation criteria
- Have different interviewers focus on different aspects of the candidate (e.g., technical skills, cultural fit, leadership)
- Require concrete examples to back up strong ratings. Do not rely solely on a “good feeling.”
2. Confirmation Bias
It’s human nature to look for proof that our first impression was right. If you instantly like (or dislike) a candidate, you might unconsciously filter out information that contradicts your initial feeling.
How to avoid it:
- Write down your gut reaction at the start, then challenge yourself to find evidence that proves you wrong
- Ask all candidates the same key questions to make comparisons fair
- Score answers against a set rubric instead of just going with your instincts
3. Recency & Similarity Bias
Two common traps:
Recency Bias – Overvaluing the last person you interviewed because they’re fresh in your mind
Similarity Bias – Favoring candidates who remind you of yourself or others on your team
Both can lead to hiring the wrong person or missing out on great talent.
How to avoid it:
- Take detailed notes during each interview so you’re not just relying on memory
- Compare each candidate against the job requirements, not just the last person you spoke with
- Actively seek out diverse perspectives. Your best hire might not be someone just like you
Avoiding these biases won’t make hiring decisions foolproof, but it will make them more objective, fair, and data-driven. And in the long run, that leads to better hires and a stronger team.
