What Nobody Tells You About the Other Side of a Technical Interview
Most interview advice focuses entirely on the candidate — how to answer behavioral questions, how to solve coding challenges under pressure, how to dress, and how to follow up. But very little is ever said about what happens on the other side of that conversation. Understanding what interviewers are actually doing — and how unprepared they often are — can be one of the most powerful advantages you bring into your next technical interview.
Having sat on both sides of the interview table multiple times over the past decade, the reality is often far messier, more human, and more improvised than candidates ever realize. If you've recently received a rejection with no explanation, what follows might finally give you some answers.
The Rise of AI Screening Rounds
Before diving into what happens with human interviewers, it's worth acknowledging a fast-growing trend: AI-conducted interviews. A growing number of companies — particularly in the early screening stages — are replacing human screeners with automated interview bots. These systems ask pre-recorded or dynamically generated questions and assess your responses using natural language processing and other machine learning tools.
This means that before you ever speak to a real person, your candidacy could already be evaluated and scored by an algorithm. If you're preparing for a technical interview, it's worth researching whether the company uses AI screening and practicing accordingly. Once you've passed that stage and reached an actual human being, a whole different set of dynamics comes into play.
Most Interviewers Have No Formal Interview Training
Here's something that surprises most job seekers: the majority of engineers and managers who conduct technical interviews have received little to no formal training on how to do so effectively. You might assume that companies have rigorous processes in place — standardized rubrics, calibration sessions, and structured evaluation frameworks. Some large tech companies do. But for most organizations, the reality looks very different.
In practice, an interviewer might be handed a rubric that was created three years ago and told to "figure it out." Or two engineers might decide in a hallway five minutes before the interview what questions they're going to ask. The questions themselves are frequently whatever the interviewer personally studied when they were last job hunting — which means the difficulty and relevance of what you're asked can vary wildly depending on who happens to be in the room that day.
This is not an excuse for poor performance, but it is an important reality check. Your rejection may have had less to do with your actual abilities and more to do with the fact that your interviewer had a bad day, asked a question they themselves weren't entirely sure how to evaluate, or had a personal bias toward a particular technical approach.
How Hiring Decisions Are Actually Made
After the interview ends and you walk out the door — or close the video call — what happens next is rarely what candidates imagine. In many companies, the debrief process is informal and heavily influenced by the loudest voice in the room. Here's a look at some common patterns:
- The gut feeling dominates: Even when rubrics exist, many interviewers default to their overall impression of the candidate. Structured evaluation frameworks are often completed after the fact to justify a feeling that was formed in the first ten minutes.
- One veto can sink a strong candidate: In companies that require hiring consensus, a single interviewer who had a bad interaction — even over something minor or subjective — can block an otherwise excellent candidate from moving forward.
- Comparison bias is real: If another candidate impressed the team right before you, you may be evaluated against that impression rather than against the actual requirements of the role.
- Recency matters more than it should: Interviewers who don't take detailed notes immediately after a session will often remember the last five minutes of an interview more clearly than anything else. How you close your interview is more important than most people realize.
What This Means for Your Technical Interview Preparation
Understanding the behind-the-scenes reality of technical interviews should change how you prepare. Here are practical strategies that account for the human imperfections of the hiring process:
- Make your thought process visible: Since interviewers vary in how they evaluate problem-solving, narrating your reasoning out loud ensures that even an undertrained interviewer can see your value. Don't assume a correct final answer is enough — show your work every step of the way.
- Build rapport deliberately: Given how much gut feeling influences hiring decisions, likability and communication clarity matter enormously. This doesn't mean being fake — it means being engaged, asking thoughtful questions, and treating the conversation as a two-way dialogue.
- Close with impact: Because recency bias is a real factor in how interviewers remember candidates, pay close attention to how you end the interview. Summarize your enthusiasm for the role, ask a meaningful question, and leave the interviewer with a clear and positive final impression.
- Don't over-index on one rejection: If you didn't get the job, it may have had nothing to do with your qualifications. The process itself is imperfect. Use feedback where available, identify any genuine areas for improvement, and keep moving forward.
The Interviewer Is Often Just as Nervous as You Are
One of the most humanizing things to remember is that the person across from you is likely not entirely comfortable either. Interviewing candidates is a skill, and like all skills, it requires practice and experience to develop. Many engineers who are technically brilliant are poor interviewers simply because they haven't had the opportunity — or training — to become good at it.
When you walk into your next technical interview, remember that you're not facing a perfectly calibrated evaluation machine. You're talking to a human being who is doing their best with the tools and time they have. Your job is to make it as easy as possible for them to recognize your value — and now that you know what's happening behind the curtain, you're far better equipped to do exactly that.
