A couple of weeks ago, more than 500 IBM employees across China, Japan, India, The Middle East, Germany, France, Italy, UK, Canada, Brazil and the United States got together to solve some pressing customer problems from the comfort of their homes.

The goal? To infuse Artificial Intelligence into existing products.

How? Through a virtual AI-a-thon.

Now, don’t be surprised. Everything around us is going virtual and so are hackathons.

Most people know hackathons as an event where people come together to a physical location to solve real-world problems with technology. And doing this virtually has its own benefits, said Jeffrey Dare, Advisory software engineer at IBM and one of the organizers of the IBM virtual hackathon.

IBM virtual hackathon

For those who are new to virtual hackathons, Jeff said you’d need to keep these points in mind for successful execution:

  1. Know your target audience and have your problem defined to a granular level. If your employees don’t understand what the problem is in the first place, you may not reap the benefits of an activity like this. Also, have your judging criteria set and announce it before the hackathon starts.
  2. If you are running an AI hackathon as IBM did, you must have your data sets ready. Also, make sure you invest in the right infrastructure. In the case of a virtual hackathon, signing up for a hackathon software such as HackerEarth can make the process so much easier.
  3. Run a hackathon once every quarter or once every 6 months. But make sure it is not too frequent as it could bring down your employees’ interest levels.

Jeff said there were 3 key benefits that clearly placed this model above the traditional one:

  • “For starters, the virtual hackathon was really engaging. Most employees don’t want to travel to a different location. In fact, the coding phase started during the lockdown and we were skeptical if things would work out or not. But it sure did and the employees loved this model for the flexibility it offered.”
  • “It helped bring the global IBM team together. We encouraged our employees to form a team as diverse as possible. Imagine someone sitting out of China brainstorming with an employee based out of IBM Brazil! Virtual was the only way it would work and it did wonders to keep our employees engaged.”
  • “Managing the hackathon was a cakewalk. The HackerEarth platform did all the heavy lifting for us and with no logistics to take care of, it was a huge relief for an organizer like me.”

The result? Most of the solutions solved our customers' problems. We were able to move all viable solutions into production,” said Jeff.

“In fact, one of the judging criteria we have is the hack’s applicability. So yes, we have long term benefits from running hackathons like these. Since it was virtual, we were able to scale the hackathon without worrying about logistics.”

Running internal innovation campaigns is an excellent way to engage talent and have a surge in creativity and output. Here is HackerEarth’s 7 point guide to hosting the perfect virtual hackathon:

  • Define a clear objective for the hackathon. It could be a solution for a real-world challenge your company is facing or to engage with your current workforce or both.
  • There is no harm in over-communicating. It is necessary to over-communicate timing and expectations and ensure everyone is engaged during the virtual hackathon.
  • Bring in as many employees as you can. Trust us, the more people on board, the better the outcome.
  • Let participants know the hackathon protocols and judging criteria in advance.
  • Keep the hackathon fluid. Let people have fun while they work on making your products better. So if they need a break or if they want to have a fun session in between, let them.
  • Have informative sessions to engage with the team during a hackathon. This could be an expert webinar or even a fun online game that can be played to ensure everyone is in high spirits during the hackathon.
  • Invest in the right tech. With the right tools, you can make the distance seem smaller and virtually bring people from around the world closer to ideate and create solutions.

Why AI Interviews Are Becoming Standard Practice in Technical Hiring

Why AI Interviews Are Becoming Standard Practice in Technical Hiring

What Engineering Leaders and Talent Teams Need to Know in 2026

Technical hiring has a throughput problem. The average senior engineer spends over 15 hours a week on candidate screening, time pulled directly from product work. Recruiters manage inconsistent evaluation standards across interviewers, scheduling bottlenecks across time zones, and drop-off rates that increase every time a candidate waits too long to hear back.

AI-powered interviews have emerged as a direct response to these operational challenges, and in 2026, they have moved from experimental to mainstream.

This is not about replacing human judgment in hiring. It is about how AI interviews fit into a well-designed technical hiring process, what research shows about their impact, and what to consider when evaluating platforms.

AI Interviews Remove the Limits of Human Screening

The most immediate value of AI-powered interviews is capacity. A single AI interviewer can screen thousands of candidates simultaneously, across time zones, without scheduling conflicts, and with consistent evaluation standards. For organizations running high-volume technical hiring or expanding globally, this eliminates the constraints imposed by human bandwidth.

Consistency is another key advantage. Human screening can vary across interviewers, days, and even times of day. AI interviews apply the same rubric to every candidate, every time. This ensures fairness and produces higher-quality data for hiring decisions downstream.

Cost savings are also significant. Automating repetitive screening through AI can reduce recruitment costs by up to 30 percent, freeing senior engineering and recruitment teams to focus on areas where human judgment adds the most value, such as final technical rounds, culture fit, and candidate closing.

What the Data Actually Tells Us

A large-scale study by Chicago Booth's Center for Applied Artificial Intelligence screened over 70,000 applicants using AI-led interviews. The results challenge the assumption that automation compromises hiring quality.

Organizations using AI interviews reported:

  • 12% more job offers extended
  • 18% more candidates starting their roles
  • 16% higher 30-day retention rates

These improvements suggest AI screening, when implemented properly, surfaces better-matched candidates without reducing quality. The structured, bias-reduced evaluation process also increases access to qualified candidates who might otherwise be filtered out.

Candidate feedback is also important. When offered a choice between a human recruiter and an AI interviewer, 78% of applicants preferred the AI. They cited fairness, efficiency, and schedule flexibility as the main reasons. Transparent AI interview processes improve candidate experience rather than harm it.

What Really Happens in an AI Interview

Modern AI interview platforms combine multiple technologies.

Natural language processing allows systems to understand responses contextually, not just match keywords. The system can probe deeper when a candidate mentions a particular solution or concept, ensuring dynamic, adaptive interviews.

For technical roles, AI platforms often include live coding environments across 30+ programming languages. These platforms assess code quality, problem-solving, efficiency, and framework familiarity. Question libraries, such as HackerEarth’s 25,000+ vetted questions, are mapped to specific skills and roles.

Some platforms use video avatar technology to simulate a more natural interaction. This reduces candidate anxiety and encourages authentic responses, producing better evaluation data.

AI systems also mask personal identifiers to prevent unconscious bias. Candidate evaluation is based solely on demonstrated ability.

Where Human Judgment Remains Essential

AI interviews handle high-volume screening and structured evaluation, but human judgment remains critical. Final decisions, culture fit assessments, and relationship-building still require human oversight.

AI complements human recruiters by allowing them to focus on high-impact decisions rather than repetitive tasks.

Bias mitigation is another consideration. Leading platforms implement diverse training datasets, bias audits, and transparent evaluation methods. Organizations should verify how vendors handle these aspects.

What to Evaluate When Selecting a Platform

Not all AI interview platforms are equal. Key criteria include:

  • Question library depth: Role-specific, vetted questions provide better assessment signals
  • Adaptive questioning: Follow-up questions based on responses reveal deeper insights
  • Proctoring and security: Real-time monitoring, AI-likeness detection, and secure browsers are essential
  • Integration with ATS: Smooth integration prevents operational friction
  • Candidate experience: Lifelike avatars and intuitive interfaces reduce drop-offs and enhance employer brand
  • Data security and compliance: Robust encryption and privacy compliance are mandatory
  • Proven enterprise adoption: Platforms used by top companies validate reliability and scalability

Getting Implementation Right

Successful AI interview deployment focuses on process design, not just software.

  • Define scope clearly: AI works best in specific stages of the hiring funnel, typically after initial applications and before final human-led rounds
  • Be transparent with candidates: Inform applicants about AI interviews to improve trust and experience
  • Correlate AI scores with outcomes: Track performance, retention, and satisfaction to refine the process
  • Invest in recruiter training: Recruiters shift from screening to interpreting AI insights and focusing on high-value interactions

So, What’s the Real Impact?

AI interviews solve measurable problems, including limited interviewer bandwidth, inconsistent evaluation, scheduling friction, and geographic constraints. Research supports their effectiveness as a scalable, structured layer that enhances screening quality without replacing human judgment.

For organizations hiring technical talent at scale in 2026, the focus is on how to implement AI-powered interviews effectively rather than whether to adopt them. The tools, evidence, and candidate acceptance are already in place. Success comes from thoughtful process design.

HackerEarth offers AI-powered technical assessments and interviews, including OnScreen, its always-on AI interview agent with lifelike avatars and end-to-end proctoring. It serves 500+ enterprise customers globally, including Walmart, Amazon, Barclays, GE, and Siemens, supporting 100+ skills, 37 programming languages, and 25,000+ vetted questions.

Introducing HackerEarth OnScreen: AI-powered interviews, around the clock

Introducing HackerEarth OnScreen: AI-powered interviews, around the clock

Tech hiring has a blind spot, and it's not the resume pile, the take-home tests, or even the interview itself. It's the gap between when a great candidate applies and when your team is available to talk to them. That gap costs you more top talent than any competitor does.

Today, HackerEarth OnScreen closes it permanently.

The real cost of scheduling friction

Most companies assume they lose candidates to better offers. The data tells a different story.

A developer weighing two opportunities almost always moves forward with the company that responded first, not the one that sent a calendar invite for Thursday. AI-generated resumes have flooded inboxes, making screening harder. Engineering teams the people best positioned to evaluate technical depth have limited hours. Recruiters are under pressure to move faster while maintaining quality.

Something had to change.

What OnScreen does

OnScreen doesn't just automate scheduling. It conducts the interview.

A candidate who applies at 11 PM gets a full interview before Monday morning through lifelike AI avatars with built-in identity verification and proctoring. The experience is a genuine two-way conversation: dynamic, adaptive, and role-calibrated. This is not a chatbot filling out a scorecard.

One enterprise customer screened more than 2,000 candidates in a single weekend with complete consistency and zero interviewer bias.

"Recruiters are under pressure more than ever. The volume of applicants has surged, AI-generated resumes have made initial screening harder, and the risk of missing the right candidate keeps climbing. OnScreen was built so that no qualified candidate is overlooked because nobody was available to interview them."
— Vikas Aditya, CEO, HackerEarth

Three capabilities, combined for the first time

In-depth interviewing that evaluates reasoning, not recall.
OnScreen conducts dynamic technical conversations that adapt to how each candidate responds. It probes the depth of knowledge, follows threads, and evaluates the quality of thinking behind each answer not just whether the answer is correct. Every interview runs on a deterministic framework: the same structure for every candidate and no panel-to-panel variation.

Integrated proctoring, built in from the start:
Enterprise-grade proctoring is woven directly into the interview flow not bolted on as an afterthought. Legitimate candidates won't notice it. The ones who shouldn't be in your pipeline will.

KYC-grade candidate verification
OnScreen brings identity verification standards from financial services into technical hiring. Proxy candidates, resume misrepresentation, and skills that don't match the application – all three gaps were closed at the source.

What hiring teams are saying

"Before OnScreen, we had no reliable way to measure candidate quality, especially with the rise of AI-generated CVs. Now, screening is far more objective. Roles that previously took much longer are now being closed within three to four weeks."
— Pawan Kuldip, Head of Human Resources, Discover Dollar Inc.

Built for everyone in the process

For engineering teams:
Fewer hours on screening calls. Senior engineers focus on final-round conversations, not first-pass filters.

For recruiters:
Pipelines that move. Candidates evaluated and scored before the week starts.

For candidates:
A consistent, skills-first experience, regardless of when they apply or where they're located.

OnScreen integrates directly into HackerEarth's existing platform alongside Hiring Challenges, Technical Assessments, and FaceCode. It extends your interviewing capacity without adding headcount.

The hiring bar just got higher. Everywhere.

Top talent expects swift, fair processes. Companies that deliver both, at scale, around the clock, will hire the engineers everyone else is still scheduling calls about.

OnScreen is now live for enterprise customers. Request access at hackerearth.com/ai/onscreen.

HackerEarth powers technical hiring at Google, Amazon, Microsoft, and 500+ global enterprises. The platform supports 10M+ developers across 1,000+ skills and 40+ programming languages.

What It Takes to Keep Gen Z Engaged and Growing at Work

What It Takes to Keep Gen Z Engaged and Growing at Work

Engaging Gen Z employees is no longer an HR checkbox. It's a competitive advantage.

Companies that get this right aren’t just filling roles. They’re building future-ready teams, deepening loyalty, and winning the talent market before competitors even realize they’re losing it.

Why Gen Z is Rewriting the Rules

Gen Z didn’t just enter the workforce. They arrived with a different operating system.

  • They’ve grown up with instant access, real-time feedback, and limitless choice. When work feels slow, rigid, or disconnected, they don’t wait it out. They move on. Retention becomes a live problem, not a future one.
  • They expect technology to be intuitive and fast, communication to be direct and low-friction, and their employer to reflect values in daily action, not just annual reports.

The consequence: Outdated systems and poor employee experiences don’t just frustrate Gen Z. They accelerate attrition.

Millennials vs Gen Z: Similar Generation, Different Expectations

These two cohorts are often grouped together. They shouldn’t be.

The distinction matters because solutions designed for Millennials often fall flat for Gen Z. Understanding who you’re designing for is where effective engagement strategy begins.

Gen Z’s Relationship with Loyalty

Loyalty, for Gen Z, is earned, not assumed.

  • They challenge outdated processes and push for tech-enabled workflows.
  • They constantly evaluate whether their current role offers the growth, flexibility, and purpose they need. If it doesn’t, they start looking elsewhere.

Key insight: This isn’t disloyalty. It’s clarity about what they want. Organizations that align experiences with these expectations gain a competitive edge.

  • High turnover is the cost of ignoring this.
  • Stronger teams are the reward for getting it right.

What Actually Works

1. Rethink Workplace Technology

  • Outdated tools may be invisible to older employees, but Gen Z sees them immediately.
  • Modern HR tech and collaboration platforms improve efficiency and signal investment in people.
  • Invest in tools that reduce friction and enhance daily experience, not just track performance.

2. Flexibility with Clear Accountability

  • Gen Z values autonomy, but also needs clarity to thrive.
  • Hybrid and remote models work when paired with well-defined goals and explicit ownership.
  • Focus on outcomes, not hours. Autonomy with accountability is a combination Gen Z respects.

3. Continuous Feedback, Not Annual Reviews

  • Annual performance reviews feel outdated. Gen Z expects real-time feedback loops.
  • Frequent, actionable feedback helps employees improve faster and signals that their growth matters.
  • Make feedback a weekly habit, not a twice-yearly event.

4. Make Growth Visible

  • If career paths aren’t clear, Gen Z won’t wait. They’ll look elsewhere.
  • Internal mobility, structured learning paths, and reskilling opportunities signal future potential.
  • Invest in learning and development and make career trajectories explicit.

5. Build Real Belonging

  • Inclusion must show up in daily interactions, not just company values documents.
  • Inclusive environments where diverse perspectives are genuinely sought produce better decisions and stronger engagement.
  • Gen Z quickly notices when DEI is performative. Build it into everyday interactions.

6. Connect Work to Purpose

  • Gen Z wants to see how their work matters in a direct, traceable way.
  • Linking individual roles to tangible business outcomes increases ownership and engagement.
  • Purpose-driven work isn’t a perk. It’s a retention strategy.

7. Prioritize Well-Being

  • Burnout is a performance problem before it becomes attrition.
  • Mental health support, sustainable workloads, and genuine flexibility reduce stress and sustain engagement.
  • Policies must be real in practice. Gaps erode trust.

How to Attract Gen Z from the Start

Job Descriptions That Tell the Truth

  • Generic postings don’t convert Gen Z candidates. They want specifics: remote or hybrid expectations, real growth opportunities, and culture in practice.
  • Transparent job descriptions attract better-fit candidates and reduce early attrition.

Skills Over Experience

  • Gen Z and organizations hiring them increasingly value potential over tenure.
  • Skills-based hiring opens access to a broader, more diverse talent pool and builds teams equipped for change.
  • Hire for capability and future-readiness, not just years on a resume.

The Bottom Line

Retaining Gen Z isn’t about perks. It’s about rethinking the employee experience from the ground up.

  • Flexibility without accountability fails.
  • Purpose without visibility is hollow.
  • Growth that isn’t visible or structured drives attrition faster than most organizations realize.

The payoff: When organizations combine the right technology, real flexibility, continuous feedback, visible growth paths, and genuine inclusion:

  • Gen Z doesn’t just stay. They perform at a higher level.
  • Adaptive, future-forward thinking compounds over time.

That’s what separates organizations that thrive in today’s talent market from those constantly replacing people who left for somewhere better.
