Technical interviews are a make-or-break part of hiring for engineering, software, IT, and science roles. This guide answers the core question what is a technical interview, shows how interviewers think, breaks down common formats, and gives practical, prioritized steps you can use today to improve performance in interviews, sales conversations that require technical explanation, or academic assessments.
What is a technical interview and how should I define it
A clear, practical definition helps you prepare deliberately. At its core, what is a technical interview is a performance-focused assessment that tests technical skills, problem-solving, domain knowledge, and communication under pressure. Unlike behavioral interviews that focus on past actions and cultural fit, technical interviews probe how you reason, design, and implement solutions in real time — through coding, whiteboarding, discussing projects, or answering knowledge-based questions Karat Guide, Northeastern Careers.
Key elements to remember about what is a technical interview:
It evaluates applied skills (coding, systems design, troubleshooting) rather than only credentials.
It rewards clear thinking and a defensible process as much as correct final answers.
It mimics real-world tasks you’d do on the job — so demonstrating how you work is as important as what you know.
What is a technical interview and why does it matter beyond hiring
When you ask what is a technical interview, you should also ask why it matters. These interviews are not just gatekeepers for jobs; they mirror how you'll communicate and collaborate in professional life. For example:
Sales calls often require explaining complex solutions simply; technical interviews test that same clarity of explanation.
College or research interviews require demonstrating depth of field knowledge and the ability to walk someone through reasoning, similar to a technical interview.CodeSignal blog
Thinking in terms of what is a technical interview helps reframe preparation: you are practicing the skills you’ll use day-to-day — problem decomposition, trade-off discussion, and collaborative debugging — not just cramming trivia.
What is a technical interview and what common formats can I expect
Understanding formats is one of the best ways to reduce anxiety about what is a technical interview. Common structures include:
Live coding (online IDEs such as CoderPad, 30–60 minutes): You’ll be asked to implement an algorithm or feature in real time. Interviewers evaluate correctness, style, and how you handle edge cases Karat Guide.
Whiteboard or paper sessions: Focused on design, algorithms, or architecture; emphasis on explaining choices and drawing clear diagrams.
Pair programming: Collaborative coding with the interviewer to solve a problem — communication and adaptability are key CodeSignal blog.
Conversational/knowledge-based: Questions about CS fundamentals, system design, or past projects; suitable for senior roles or domain specialists Northeastern Careers.
Multi-stage pipelines: Phone screen or online test → technical interview → onsite/team fit round. Knowing the stage clarifies what is being evaluated at each step.
Each format tests similar core traits but in different ways — practicing the specific format you’ll face is high-leverage preparation.
What is a technical interview and what do interviewers evaluate
To prepare efficiently, you must know what interviewers look for when they ask what is a technical interview:
Technical expertise: correctness, familiarity with tools and languages, and sound engineering principles.
Problem-solving: how you break down problems, handle constraints, and iterate on solutions.
Communication: thinking aloud, justifying choices, and asking clarifying questions.
Collaboration and mindset: accepting hints, responding to feedback, and showing curiosity.
Stress handling: consistent approach under time pressure and ambiguity Karat Guide, CodeSignal blog.
Interviewers often prefer a candidate who can explain a reasonable approach clearly over one who arrives at a perfect solution in silence.
What is a technical interview and what is the typical flow of one
Knowing the usual flow answers practical questions about timing and priorities in what is a technical interview. A canonical technical interview often follows these stages:
Pre-interview prep: Candidate receives problem context or prompt; interviewer outlines time and expectations.
Introductions (2–5 minutes): Quick hello, confirm logistics, share the problem scope.
Clarifying questions (2–5 minutes): Candidate asks scope and constraints — essential to show you understand ambiguity handling.
Problem-solving and implementation (20–45 minutes): Design, code, and test. Verbalize your thinking and check edge cases.
Q&A and discussion (5–10 minutes): Explain trade-offs, alternative solutions, or optimizations.
Candidate questions and next steps (2–5 minutes): Ask about the role, team, or code base.
This flow is common across live coding, whiteboard, and conversational formats. Practice following the flow to keep time management and communication consistent UT Austin Careers.
What is a technical interview and what are common challenges candidates face
Answering what is a technical interview includes preparing for predictable pain points. Common challenges:
Time pressure and vague problems: Short windows test how quickly you identify core requirements and prioritize a working solution Karat Guide.
Not explaining your thought process: Silent coding looks like guessing. Interviewers want to follow your reasoning CodeSignal blog.
Technical gaps: Questions about unfamiliar libraries, algorithms, or systems can expose weaknesses. Acknowledge unknowns and demonstrate how you'd learn.
Format stress: Whiteboard anxiety, remote tool quirks, or pair-programming dynamics can derail performance Northeastern Careers.
Overlooking soft skills: Candidates sometimes ignore team-fit cues or collaboration prompts, which matter especially for senior roles.
Recognizing these challenges allows you to practice targeted coping strategies rather than vague "study harder" advice.
What is a technical interview and what actionable preparation should I follow
Practical, prioritized steps make your preparation efficient. Here’s a focused plan to answer what is a technical interview through action.
Before the interview (4–8 weeks plan):
Map the job to skills: List languages, frameworks, systems, and CS fundamentals relevant to the role.
Refresh fundamentals: Practice data structures, algorithms, and system design basics (arrays, trees, hashes, graphs, sorting, Big-O).
Practice in relevant format: Use CoderPad-style editors, whiteboards, or pair-programming sessions on platforms like LeetCode or HackerRank to simulate the real environment Karat Guide.
Mock interviews: Do full-length mock interviews with peers or platforms that provide feedback to benchmark weaknesses Pitt CareerCentral.
During the interview:
Start by asking clarifying questions: Confirm inputs, outputs, constraints, and acceptable runtimes.
Think aloud: Narrate trade-offs, edge-case checks, and why you choose one approach over another CodeSignal blog.
Prioritize working correctness: Implement core functionality first; polish later if time allows.
Use tests: Walk through examples and manual tests to catch mistakes early.
If stuck, present alternatives: Describe a simpler working solution or a roadmap for completing the task.
After the interview:
Debrief immediately: Note what went well, what blocked you, and which questions you should have asked.
Iterate your practice based on gaps: If you struggled with graph questions, add targeted practice.
Send a concise thank-you note that reiterates interest and one specific takeaway from the interview.
These steps convert the abstract query what is a technical interview into a repeatable routine that improves outcomes fast.
What is a technical interview and what are the do's and don'ts
A short, actionable ruleset clarifies common pitfalls when thinking about what is a technical interview.
Do's | Don'ts |
|---|---|
Communicate your thought process — narrate trade-offs and steps CodeSignal blog | Stay silent while coding — interviewers need to see your reasoning |
Research the company and role to tailor examples Karat Guide | Panic or give up on unknowns — describe how you'd find an answer |
Remain collaborative — invite feedback and ask yes/no clarifying questions | Ignore feedback or interviewer hints |
Ask smart clarifying questions early to narrow scope UT Austin Careers | Rush into coding without a plan |
