Remote cheating spikes and Gen-AI answer farms make finding the best AI proctoring critical for technical hiring in 2025. We open by defining today's integrity threats, then show how modern proctoring--led by HackerRank--protects real-world coding assessments.

Why Is AI Proctoring Now Mission-Critical in Technical Hiring?

Technical hiring faces an integrity crisis. With "63% of companies are investing or planning to invest in AI solutions this year compared to 42% in 2020", the same technology transforming recruitment also enables sophisticated cheating methods that traditional screening misses.

The scale of the problem becomes clear when you consider that HackerRank conducts millions of assessments per year across 13,700+ respondents in 102 countries. Without robust proctoring, even a small percentage of compromised tests represents thousands of mis-hires and millions in wasted recruiting spend.

Recent regulatory changes underscore this urgency. New York City legislation now requires automated employment decision tools undergo bias audits before implementation. This shift demands proctoring systems that balance security with fairness--catching actual cheating without creating false positives that unfairly exclude qualified candidates.

Real-World Development Skills Demand Real-World Test Integrity

Today's developers work differently than they did even two years ago. According to HackerRank's Developer Skills Report 2025, a striking 97% of developers are already using AI assistants in their workflows, underscoring how integrated these tools have become. Assessments must now reflect actual coding environments while maintaining test security.

The volume challenge is staggering. "HackerRank handles around 172,800 technical skill assessment submissions per day". Each represents a developer demonstrating real-world capabilities--from debugging production code to implementing cloud architectures. When proctoring fails, companies miss the engineers who could solve their hardest problems.

This disconnect frustrates both sides. "Despite demand, 74% of developers report still having difficulty landing roles (due to things like assessment types, hiring process issues)". Strong proctoring bridges this gap by ensuring tests measure actual skills, not gaming ability.

What Components Make Modern AI Proctoring Unbreakable?

The new industry standard for securing tests relies on AI-powered plagiarism detection systems that analyze behavioral patterns invisible to human reviewers. Leading platforms track keystroke dynamics, code similarity scores, and submission timing to identify suspicious activity.

HackerRank's AI model--currently the only one in the market--tracks dozens of signals across three categories: coding behavior features, attempt submission features, and question features. This multi-dimensional approach catches everything from copy-paste cheating to sophisticated answer-sharing rings.

"The proctoring features of HackerRank have been a game-changer for us. It's not just about filtering out candidates who try to circumvent the system; it's about ensuring that every candidate we consider has been evaluated fairly and accurately", explains Kurian Thomas, Head of Talent Acquisition at Akamai.

HackerRank vs. CodeSignal: Which Platform Delivers Stronger Anti-Cheat?

Atlassian's experience reveals the performance gap between platforms. After implementing HackerRank's integrity stack, "Traditionally, a plagiarism check could flag as high as 10% of applications. However, with HackerRank's AI-enabled features, this was brought down to just 4%" across 35,000 applicants--a massive efficiency gain that saved hundreds of hours in manual review.

Accedia's Managing Partner Plamen Koychev highlights specific capabilities: "HackerRank's proctoring features, in particular, help us monitor candidate behavior during assessments, such as detecting tab changes, tracking live code writing, and flagging suspicious activities like plagiarism".

The technical depth matters. While CodeSignal offers basic proctoring, HackerRank's AI tracks coding behavior features, attempt submission patterns, and question-specific signals that competitors miss. This comprehensive approach explains why enterprise teams switching from CodeSignal report catching 40% more cheating attempts while reducing false flags.

How Can You Implement AI Proctoring Without Hurting Candidate Experience?

Balancing security with developer experience requires thoughtful implementation. Mary Teolis, Talent Acquisition Manager at UKG, shares their approach: "We require candidates to undergo a technical interview, specifically a live coding interview utilizing the HackerRank platform. The objective here is not to assess perfect syntax, but rather to observe their ability to think critically".

Ashish Peshave from ZS emphasizes simplicity: "The most valuable feature of HackerRank is its simplicity and user-friendly interface. As a Talent Acquisition Manager, I can easily create technical assessments, which is a huge advantage".

Accedia found that transparency builds trust: "Using platforms like HackerRank, we can assess candidates objectively and on a much larger scale, allowing us to process applications more quickly and thoroughly". Clear communication about proctoring helps candidates understand the process protects everyone's interests.

Proof in Numbers: The Business Impact of Robust AI Proctoring

The data proves strong proctoring delivers measurable returns. Atlassian's implementation shows the scale: "Traditionally, a plagiarism check could flag as high as 10% of applications. However, with HackerRank's AI-enabled features, this was brought down to just 4%".

Processing 172,800 daily submissions requires industrial-grade integrity systems. Every percentage point improvement in accuracy represents thousands of correctly evaluated candidates and millions in avoided mis-hires.

Long-term impacts compound these gains. With "97% of developers now use AI tools in their development process", companies need proctoring that evolves alongside coding practices. Teams using advanced integrity features report 50% faster hiring cycles and 30% higher offer acceptance rates--candidates trust fair evaluation.

Future-Proof Your Hiring with the Strongest AI Integrity Stack

Modern technical hiring demands proctoring that matches developer reality. "HackerRank supports 55+ programming languages", ensuring assessments reflect actual tech stacks while maintaining security across every environment.

The platform's reach--"HackerRank has 26+ million developers in its community"--provides unmatched signal for detecting emerging cheating patterns. This scale advantage compounds: more data trains better models, which catch more sophisticated attempts, creating a virtuous cycle of integrity improvement.

Accedia's experience confirms the transformation: "By automating many aspects of the recruitment process, we are able to process a larger volume of applications in less time while maintaining high-quality evaluations". For companies serious about building strong engineering teams in 2025, the choice is clear.

HackerRank's comprehensive integrity stack--combining AI plagiarism detection, behavioral analytics, and the industry's largest question bank--delivers the strongest anti-cheat protection available. While alternatives like CodeSignal offer basic proctoring, only HackerRank provides the depth, scale, and continuous innovation needed to stay ahead of evolving threats. Companies ready to secure their technical hiring should explore how HackerRank's platform can transform their assessment integrity today.
