FaceCode vs. Traditional Coding Interviews: A Hiring Team's Comparison
If you're a hiring manager or recruiter running technical interviews, the format you choose shapes the quality of every hire that follows. This article compares FaceCode's live coding interview format against traditional whiteboard and take-home methods — where each works, where each fails, and how to decide which fits your hiring workflow.
Consider a pattern hiring teams see often: a candidate writes working code across multiple interview rounds, handles real-world edge cases, and still gets rejected because interviewers felt the solution "seemed overcomplicated." One candidate documented this experience on Medium after three FAANG rejections. For hiring teams, this raises a hard question: is your interview format measuring engineering ability, or performance under artificial pressure?
Traditional coding interviews frequently reward memorization and self-presentation over reasoning. AI tools now solve many of those same problems in seconds, which forces a rethink of what an interview should actually measure. Live coding assessments offer an approach that mirrors real-world problem-solving more closely — though, as we'll cover, they come with their own trade-offs.
In this article, we'll compare live coding tests against traditional methods, examine where each format falls short, and show how platforms like HackerEarth FaceCode fit into technical hiring workflows.
FaceCode vs Traditional Coding Interviews: Two Different Ways to Evaluate Developers
If you've watched candidates freeze during a whiteboard round, you've seen the core problem: the format is measuring composure under observation, not engineering judgment. Recruiters and engineering managers are increasingly questioning whether the traditional format produces reliable hiring signals.
Industry surveys point in the same direction. SHRM's 2025 Talent Trends research reports that companies using AI for hiring grew from 26% in 2024 to 43% in 2025. Hiring teams are actively experimenting with formats — including live coding interviews — that feel closer to actual work.
Let's look at how the two formats compare in practice, and what the shift means for hiring teams.
What are traditional coding interviews?
A traditional coding interview is a technical assessment format that relies on whiteboard problems, theoretical questions, or take-home assignments, where candidates solve problems in isolation without access to real tools. Related formats include in-person coding interviews, phone screens, and structured algorithm rounds — all part of the broader family of "types of coding interviews" that dominated hiring for the last two decades. Interviewers often ask candidates to solve algorithmic problems in isolation, without tools or context.
This approach creates several issues for hiring teams:
- Candidates cannot use real-world tools like IDEs or documentation
- Interviewers depend heavily on personal judgment
- Time pressure affects performance more than actual skill
- Feedback often lacks consistency across candidates
A 2023 study published in Applied Psychology examined this issue. Researchers had participants go through simulated interviews with eight traditional and eight structured questions under two conditions: one where they were instructed to present themselves honestly, and another where they were told to act like a "strong applicant."
The researchers reported that ratings improved more in the traditional interview portion than in the structured portion when candidates deliberately used impression management tactics. Interpreted straightforwardly, this suggests unstructured traditional formats can reward self-presentation alongside actual skill, though the study's authors focus on the relative structure of questions rather than a categorical indictment of traditional interviews.
Take-home assignments attempt to fix this gap, but they create new problems. Candidates spend hours on tasks without guaranteed feedback, and recruiters struggle to review submissions at scale.
In short, traditional coding interviews often test memory and self-presentation alongside real problem-solving. That disconnect can lead to weaker hiring decisions and frustrated candidates.
What are live coding interviews?
A live coding interview is a technical assessment in which candidates solve programming problems in real time within a shared coding environment. It allows interviewers to observe their problem-solving process, coding approach, and decision-making as it happens.
Here's what makes live coding useful for hiring teams:
- Real-time collaboration between the candidate and the interviewer
- Access to coding tools and environments
- Immediate feedback and clarification
- Clear visibility into the problem-solving approach
- AI-driven remote proctoring to support test integrity
That said, live coding is not a silver bullet — we'll cover its trade-offs below.
Our 2025 Technical Hiring Landscape Report suggests that the share of companies using proctoring grew from 64% in January to a peak of 77% in July. By the end of the year, nearly 2 out of 3 events (64.5%) were proctored.
Live coding also supports a more standardized coding interview framework, which helps hiring teams compare candidates fairly. This shift moves coding interviews toward a more practical and data-driven process.
Where Live Coding Interviews Fall Short
Before making the case for live coding, it's worth being honest about its limitations. FaceCode vs traditional coding interviews is not a debate with a one-sided answer — live formats introduce their own problems that recruiters and engineering managers need to plan around:
- Candidate anxiety. Being watched while coding raises stress for many candidates, especially those with performance anxiety, which can obscure actual ability. This is a common criticism raised in communities like r/ExperiencedDevs and Hacker News.
- Infrastructure dependency. Live interviews require stable internet, working audio and video, and a compatible browser. Any of these can fail mid-interview, disproportionately affecting candidates in regions with weaker connectivity.
- Interviewer skill variance. A live interview is only as good as the interviewer running it. Poor question design, leading prompts, or inconsistent rubrics can reintroduce the same subjectivity live coding is meant to reduce.
- Accessibility barriers. Candidates with speech, motor, or cognitive differences may perform worse in real-time verbal formats than in take-home or asynchronous ones.
- Sample size problem. A single 45–60 minute session is still a narrow window into how someone works over weeks and months.
Live coding solves several problems traditional interviews create, but it doesn't eliminate all of them. The strongest hiring processes typically combine formats rather than rely on any single one.
Why Live Coding Interviews Are Gaining Ground with Hiring Teams
Many candidates now prepare specifically for traditional coding interview patterns — memorizing common problems and rehearsing solutions until the round becomes a test of preparation rather than engineering ability. For hiring teams, that means the format increasingly filters for interview practice, not job performance.
So if traditional coding interviews feel disconnected from real work, what replaces them?
Live coding interviews are one answer. Mitchell Kosowski, VP of Engineering at Vouched, described the shift in a LinkedIn post, noting that live coding in tech interviews "feels like the closest thing to seeing how a candidate actually works day-to-day — how they think out loud, ask questions, and handle ambiguity — rather than testing whether they've grinded enough LeetCode."

This is a directional signal from a practitioner rather than peer-reviewed research, but it echoes what many engineering managers report internally. Here are the main arguments for live coding as a primary format:
Better visibility into problem-solving skills
When candidates solve problems live, interviewers get a direct view of how they think — how they break down ambiguity, respond to feedback, and adapt when something doesn't work the first time.
Live coding also opens the door for AI-assisted analytics to review the full problem-solving journey, not just the final solution. HackerEarth's assessments layer skill intelligence on top of these signals, giving recruiters a clearer read on candidate capability across 1,000+ skills rather than a single interview score.
Reducing (not eliminating) bias in candidate evaluation
Traditional interviews leave significant room for subjective judgment. Two interviewers might assess the same candidate very differently based on personal preferences or unconscious bias.
Live coding can reduce this variance by having every candidate work through comparable coding challenges under similar conditions, giving interviewers a shared basis for comparison. AI-assisted signals on coding patterns and decision-making add another data point. It's worth being clear: no interview format eliminates bias entirely — structured live coding simply narrows the surface area where bias creeps in.
Real-time collaboration and candidate engagement
Engineering work is collaborative, yet traditional interviews often feel like solo exams. Candidates sit in silence trying to impress while interviewers observe from a distance. Poor interview experiences travel — candidates share them widely on Glassdoor, Blind, and internal referral networks, which affects future pipeline quality.
Live coding shifts the dynamic toward conversation. Candidates can ask questions, clarify requirements, and explain their thinking as they go. This tends to produce a more natural environment where both sides engage with each other, which can support a stronger candidate experience — a growing priority for talent leaders tracking offer-acceptance rates and employer brand.
How FaceCode Fits Into the Coding Interview Process
Hiring teams are rethinking how they evaluate developers, and AI adoption is accelerating that shift. According to SHRM's 2025 Talent Trends research, companies using AI for hiring grew from 26% in 2024 to 43% in 2025. Recruiters want signals they can trust, and candidates want interviews that feel connected to real work.
Interview FaceCode is HackerEarth's live technical interviewing product, designed for interviewer-led structured interviews rather than autonomous AI-driven evaluation. As part of the broader HackerEarth platform, it gives hiring teams a way to run structured, collaborative interviews in a shared coding environment, backed by skills intelligence across 1,000+ skills.

Live interviewing capabilities
With FaceCode, interviewers and candidates collaborate inside a shared code editor while staying connected through HD video. The core capabilities include diagram boards for system design discussions, session recording with transcripts, ATS workflow integration, and access to HackerEarth's broader developer community for pipeline building.
Callout — FaceCode capabilities at a glance: - Diagram boards for system design and panel interviews. Exact panel-size limits should be confirmed with your account team. - Session recording and transcripts with the ability to mask personal information for more inclusive review. - ATS integration — specific partner integrations and configuration options should be confirmed with the HackerEarth product team based on your ATS. - Developer community access through HackerEarth's hackathons and hiring challenges for pipeline building before interviews start.
Where FaceCode may not fit: if your hiring team needs fully autonomous, AI-led coding evaluation with no live interviewer in the loop — for example, high-volume campus screening at 10,000+ candidates per cycle — an interviewer-led tool will bottleneck. HackerEarth's OnScreen product is designed for that autonomous evaluation use case; FaceCode is the interviewer-led format. Similarly, if your process relies heavily on unmoderated take-home assignments, live coding replaces rather than supplements that step, and some teams prefer to keep both.
Customizable coding exercises and templates
Every role is different, and FaceCode reflects that. Hiring teams can select from HackerEarth's question library or build their own tests based on real-world scenarios, matching the interview to the role rather than forcing candidates into generic problems.
The broader HackerEarth suite supports every stage of hiring, from candidate sourcing to upskilling. Teams can run hiring challenges, screen candidates with skill-based assessments, and engage developers through competitions.
This supports skill-based hiring, where decisions come from what candidates can actually do rather than what their resumes claim. Project-based questions, custom datasets, and role-specific test cases give teams a clearer picture of how someone will perform on the job — one factor to consider when comparing online coding interview platforms.
Code playback and interview replay
Hiring decisions often depend on small details, which fade quickly after an interview. FaceCode stores full recordings and transcripts that teams can revisit.
It includes CodePlayer, which lets you watch the coding session play back as a video. You can see how the code was written from start to finish rather than only reviewing the final result, including where a candidate paused, what they tried first, and how they corrected mistakes.
Teams can review the same session together. The option to hide candidate details keeps the focus on skills and supports fairer evaluation.

The Future of Coding Interviews
Coding interviews are changing. AI tools can now solve many of the problems candidates used to spend hours preparing for, which raises a fair question for hiring teams: if AI can pass a traditional coding interview, what is that interview actually testing?
If the answer is "syntax recall and pattern memorization," the format needs an update. If the answer is "how someone reasons, communicates, and works through ambiguity in real time," then the interview needs to be designed for that.
That's the case for live coding interviews — and the case against pretending they're a complete replacement for every other signal. The strongest hiring processes usually combine an asynchronous screening step, a live technical interview, and a system design or collaboration round.
FaceCode is built for the live technical interview piece of that stack. If your team wants to run structured, collaborative interviews that let candidates think out loud and give your team a shared record to evaluate, Try FaceCode.
FAQs
What is FaceCode, and how does it improve coding interviews?
FaceCode is a live-coding interview tool that helps hiring teams run structured, interviewer-led technical interviews. It supports real-time coding, HD video, panel formats, recordings, and transcripts, giving interviewers a shared, reviewable record of a candidate's problem-solving process. It is interviewer-led rather than an autonomous AI evaluator — for autonomous AI-led evaluation, HackerEarth's OnScreen product covers a different use case.
How does FaceCode support consistent candidate evaluation?
FaceCode supports structured interviews with shared coding environments, recordings, transcripts, and CodePlayer session replay. Interviewers can apply consistent rubrics across candidates and revisit sessions to compare decisions.
What are the advantages of live coding interviews over traditional methods?
Live coding interviews show how candidates think and solve problems in real time rather than testing memorized answers. They allow candidates to explain their approach and ask clarifying questions. They also come with real trade-offs — anxiety, infrastructure requirements, and interviewer skill variance — so most hiring teams use them as part of a multi-step process.
How can FaceCode help reduce hiring bias during coding interviews?
FaceCode supports structured interviews with consistent scoring criteria and the option to mask candidate details during evaluation. This narrows some surfaces where bias appears, though no interview format removes bias entirely — process design and interviewer training also matter.
Can FaceCode integrate with my existing ATS (Applicant Tracking System)?
FaceCode is designed to fit into existing hiring workflows and connect with common ATS platforms. Confirm specific integration partners and configuration details with the HackerEarth product team based on your current stack.
How does live coding change how fundamentals like algorithms and system design are assessed?
Live coding environments change what "assessing fundamentals" looks like. Instead of grading whether a candidate can recall Merge Sort or Binary Search from memory, interviewers can watch how the candidate reasons about which approach fits the problem, adjusts when constraints change, and communicates trade-offs. For system design rounds, tools like diagram boards let interviewers evaluate architectural thinking in real time rather than reading a static submission. The fundamentals still matter — how you assess them changes.
What are structured learning resources like Grokking the Coding Interview vs AlgoMonster useful for in hiring?
Structured learning platforms like Grokking the Coding Interview and AlgoMonster are candidate-preparation tools rather than hiring tools. For hiring teams, they're relevant context: candidates who prepare heavily through pattern-based resources may perform strongly on traditional pattern-matching questions but less strongly on ambiguous, real-world problems. Interview formats that reward reasoning over pattern recall — like live coding on realistic problems — tend to be less easily gamed by preparation platforms alone.
What are the disadvantages of face-to-face structured interviews?
Structured face-to-face interviews reduce variance but come with trade-offs: they can feel rigid, they favor candidates comfortable with performative speaking, they scale poorly across time zones, and they depend heavily on interviewer training. They also don't remove bias — they narrow it. This is a core reason many hiring teams pair structured live formats with asynchronous work samples or take-home tasks.
