What Nobody Tells You About Technical Interviews
Most interview advice focuses entirely on the candidate: how to answer behavioral questions, how to solve coding challenges under pressure, how to follow up with a thank-you email. But there is a whole other side of the table that rarely gets discussed — the interviewer's side. And understanding what is happening there can fundamentally change how you prepare.
Having sat on both sides of the interview table multiple times over the past decade, one thing becomes immediately clear: the process is far messier than most candidates ever imagine. If you recently received a rejection and couldn't figure out why, what follows might finally give you some answers.
Most Interviewers Are Not Formally Trained
Here is something that might surprise you: many companies have no standardized interview training for their engineers or hiring managers. Candidates spend weeks grinding LeetCode problems and rehearsing their STAR-method answers, while the person on the other side of the Zoom call may have pulled up a three-year-old rubric an hour before the meeting.
In practice, interviewer prep can look something like this: a manager sends a Slack message to a senior engineer saying, "Hey, can you hop on an interview with me Thursday?" The engineer agrees, looks at a shared doc from a previous hiring cycle, and improvises the rest. Questions are often whatever the interviewer personally studied when they were last job hunting, which means the process can vary wildly depending on who happens to be available that day.
This is not a knock on interviewers — most are talented professionals who are simply balancing hiring responsibilities on top of full-time engineering work. But it does mean that the interview experience you have at a given company can differ dramatically depending on your interviewer, even within the same team.
The Rise of AI-Driven Screening Rounds
Before we go further, it is worth acknowledging a growing reality in the hiring landscape: a significant and increasing share of job seekers now report being interviewed by an AI system at some point in the process, particularly during early screening rounds. Automated video interviews, chatbot assessments, and AI-scored coding challenges are becoming common at large tech companies.
Everything discussed in this article assumes you have made it past any automated filters and are sitting across from an actual human being. If you are facing an AI screening round, the dynamics are different — but that is a topic for another article entirely.
What Interviewers Are Really Evaluating
When a technical interviewer walks into a session, they are typically trying to answer a small number of core questions about you:
- Can you solve problems under pressure? They want to see your thought process, not just your final answer. Talking through your reasoning out loud is more valuable than you might think.
- Would working with you be pleasant? Culture fit and communication style matter enormously, sometimes more than technical score.
- Do you ask good questions? Engineers who clarify requirements before charging ahead are seen as more experienced and collaborative.
- Can you handle not knowing something? Saying "I'm not sure, but here's how I would approach finding out" often reads better than a wrong answer delivered with false confidence.
The challenge is that these criteria are rarely written down anywhere the candidate can see them. Interviewers are often using a subjective gut feeling shaped by their own experience and biases, then reverse-engineering a score to fit a rubric afterward.
How Hiring Decisions Actually Get Made
After your interview, something interesting happens: a debrief meeting takes place, often within 24 to 48 hours. Everyone who spoke with you shares their notes and impressions. This is where the real decision gets made — and where things can get complicated.
Strong advocates matter. If one interviewer is genuinely excited about your potential, they can carry significant weight in a room full of neutral opinions. Conversely, a single strong objection from one interviewer — even over something minor — can be enough to sink an otherwise solid candidacy at companies that require consensus hiring.
Timing also plays an unexpected role. If your interview happened the same week as a budget review, a team reshuffling, or a sudden change in headcount approval, you might have been passed over for reasons that had nothing to do with your performance. The hiring pipeline is noisier than it looks from the outside.
How to Use This Knowledge to Your Advantage
Understanding what is happening on the other side of the table gives you a real edge. Here are a few practical ways to apply these insights:
- Make your interviewer's job easy. Structure your answers clearly, summarize your thinking, and signal explicitly when you are moving from one part of your response to another. Interviewers who are juggling a messy rubric will appreciate the clarity.
- Build rapport early. Small talk at the start of an interview is not fluff — it is where an interviewer begins forming their impression of you as a colleague. Be warm, curious, and engaged.
- Ask questions that demonstrate technical depth. Thoughtful questions about architecture decisions, team workflows, or technical debt show interviewers exactly the kind of engineer you are.
- Do not over-index on rejection. If you were turned down, it may have had nothing to do with your technical ability. Learn what you can, then move forward.
The Takeaway
Technical interviews are a two-way street, even if most of the advice you read suggests otherwise. The process on the interviewer's side is often less polished, less consistent, and more human than candidates expect. By understanding the pressures, biases, and constraints that interviewers operate under, you can walk into your next session with a more realistic picture of what success looks like — and a much stronger strategy for achieving it.
The best candidates are not just technically prepared. They understand the room they are walking into. Now you do too.
