What I’ve Learned from Technical Interviews

After interviewing several candidates over the past months, I noticed a common pattern: many people freeze not because they lack knowledge, but because of mindset. Technical interviews aren’t exams — they’re windows into how someone works, communicates, and solves problems in real life.

October 4, 2025

While conducting technical interviews, I started realizing that many candidates approach the process like a school test. They try to get every answer right, speak only when sure, and aim for perfection. But that mindset misses the point entirely.

Technical interviews are not exams. They’re simulations of collaboration and problem-solving. Once candidates understand that, the entire dynamic changes — for both sides.

What interviewers actually care about

When an interviewer spends an hour or more with a candidate, the goal isn’t to check for memorized answers or trick questions. It’s to see how the person behaves in real-world problem-solving. Things like:

  • How they reason through complex situations.
  • How they react when they don’t know something.
  • How they handle mistakes or dead ends.
  • How they communicate their thought process.
  • How they collaborate when guided or challenged.

It’s less about what they know and more about how they work.

1. Mistakes are part of the process

One of the biggest misconceptions I see is that making a mistake means failure. But for interviewers, mistakes often reveal far more than correct answers — they show resilience and self-awareness.

Here’s what I usually notice:

  • 🔴 Candidate A makes a mistake, gets visibly nervous, and doubles down instead of reassessing.
  • 🟢 Candidate B pauses, says something like “Wait, I think I went off here”, rethinks, and adjusts course.

The second one demonstrates maturity and problem-solving under pressure — qualities every team values.

2. Communication is everything

I can’t emphasize this enough: how candidates communicate often matters more than whether they know the exact syntax of something.

Good communication turns an interview into a collaboration instead of an interrogation. It lets the interviewer help, clarify, and see how you think.

What makes communication stand out

  • Thinking out loud: letting me follow your logic step by step.
  • Explaining small choices: “I’ll go this route because it’s simpler to maintain”.
  • Inviting input: “I can explore A or B — which direction sounds better for this scenario?”

Even when candidates hit a dead end, that openness makes a strong impression. It shows teamwork and humility — the traits of someone great to work with.

3. Ask better questions

Another key insight: the best candidates ask smart, structured questions. They don’t just ask “what should I do?” — they show they’ve thought things through.

Weak question:

“Which path should I take?”

Stronger question:

“I’m considering two paths — A and B.
A is more straightforward but less scalable.
B is cleaner long term but adds complexity now.
Which trade-off makes more sense in this context?”

The second approach shows reasoning and self-awareness. It also builds a sense of collaboration, rather than dependence on the interviewer’s guidance.

4. Respect the interviewer’s time

Interviews take focus, preparation, and time away from daily work. When a candidate is organized, communicates clearly, and stays engaged, that energy is instantly noticeable — and appreciated.

How to show respect in practice:

  • Be clear and direct, but conversational.
  • Structure your thoughts before diving into code.
  • Keep the session fluid and collaborative.
  • Bring good energy — people remember how you made them feel.

5. Train beyond algorithms

Many candidates spend all their prep time grinding algorithm problems, but they forget to train what really shows up in interviews: communication, reasoning, and presence.

What I recommend practicing

  • Explain your approach to a problem as if teaching a beginner.
  • Redo a simple coding task and narrate your thought process aloud.
  • Record yourself explaining something — it’s eye-opening to hear your clarity (or lack of it).

The goal is to feel natural under mild pressure, not robotic or rehearsed.

6. The big picture

After interviewing many candidates, I’ve learned that technical interviews are less about getting everything right and more about showing how you think, adapt, and interact.

  • Resilient when mistakes happen.
  • Clear in explaining reasoning.
  • Collaborative in discussion.
  • Respectful of the other person’s time.
  • Structured in how ideas are presented.

When candidates shift their mindset from “I need to ace this” to “I need to work through this”, they instantly stand out. It shows confidence, maturity, and a team-first mentality.

And honestly, that’s what every good interviewer is looking for — not perfection, but professionalism and presence.


⏱ Reading time: ~5 minutes

📌 Quick checklist before your next interview

  • Am I ready to explain my reasoning out loud?
  • Do I know how to recover from mistakes calmly?
  • Do I have examples of structured questions?
  • Am I focused on collaboration, not perfection?
