Hackathons: Attract, Engage, Hire & Train Top Talent

Ever since the pandemic hit, employers have had to fill positions without requiring candidates to go through an extensive in-person interview process. As a result, many companies have turned to virtual hiring programs as well as hackathons to reach their recruiting goals. A study found that 40% of companies use a hackathon hiring process as part of their recruitment strategies.

So what exactly is a hackathon and how to conduct one?

What is Hackathon?

Hackathons are events where computer programmers and other technology professionals come together to create new products or solve technological problems. They typically last for several hours and sometimes even go up to several days. Teams are often formed at hackathons, which are made up of people with different skill sets. At the end of the event, these teams present their product or solution to a panel of judges. Hackathon hiring processes are usually sponsored by companies that want to promote innovation within the tech world.

Types of Hackathons

The top 2 types of hackathons are external hackathons and internal hackathons:

External hackathons:

At an external hackathon hiring process, participants create their own projects. They might work on coding tools, websites, or mobile apps that can be used by other people in the tech world. Employers sponsor these events to find new hires and engage with potential recruits. They also offer a valuable learning experience for attendees or students who may be interested in pursuing a career in technology.

Hackathons For Hiring Top Talent: What Do The Numbers Say?

Here’s a closer look at how these hackathons can benefit your organization.

External Hackathons

With hackathon recruiting, companies are replacing the intimidating interview setting with a competitive drill where candidates can show their skills. As recruiters get to observe them apply these abilities in real-time they are better placed at analyzing candidate competency and making informed hiring decisions. These projects can be used as portfolios to help participants build their brands and show off what they’ve accomplished. Participants could also use these products as a way to gain exposure or to see if it is feasible for them to turn the project into a business venture.

Its benefits include:

1. Build a diverse team from all around the world:

The hackathon hiring process creates a unique opportunity for people from all over the world to come together and work on a project. Participants who network with these people during hackathons might be able to add them as contacts when they return to the office, thus building company connections that would not have been possible otherwise.

2. Join hands with industry experts:

Industry experts and sponsors of the event actively participate as judges or mentors. This allows them to network with new people and gain access to the latest trends in the tech industry. Attendees make valuable contacts at hackathons which can be beneficial for your company even after the events are over.

3. Expand your developer community:

Companies use the hackathon hiring process to attract developers who might not otherwise come in contact with your brand. This offers a way for you to interact with the tech community and establish new relationships. It also allows you to identify potential candidates who might be looking for a job opportunity

4. Find the best talent for your business:

The hackathon hiring process offers a way to identify the best developer talent in the industry. It also helps you create a larger pool of qualified applicants for future roles. In addition to hiring developers, hackathons can help you identify other employees as well as interns who would be a good fit for your team.

Because hackathons are team-based events, it also allows you to see how candidates interact with their peers. You can assess how comfortable and confident they feel when working alongside others and whether they’re open to feedback and suggestions.

5. Boost corporate branding:

Hackathons offer a great opportunity to increase awareness about your brand and what you have to offer. Corporate hackathon ideas allow companies to showcase their product or service in a new way that is often more effective than advertising campaigns.

Hackathons also offer a valuable way for companies to crowdsource ideas from people who matter the most. People from different departments and backgrounds can share their thoughts on improving daily operations, which allows your team to come up with solutions that would not have been possible otherwise.

Internal Hackathons

Most companies hold internal hackathons for team building. They can be a great way to get your employees excited about their work while allowing them to collaborate and build relationships with one another outside of the normal office environment. Internal hackathon ideas are perfect for tapping into the skills of the company’s workforce.

Participants could be tasked with creating an internal service or tool that solves a particular problem within the company, such as reducing costs or increasing efficiency. At the same time, learning and development programs are also offered at these events which can help employees develop new skills.

This is how it benefits your company:

1. Boosts morale:

Hackathons are a great way to get employees excited about their work again. It creates an environment that fosters teamwork and allows people to interact with each other in ways they normally wouldn’t be able to inside the office. It builds stronger connections between employees which can improve workplace satisfaction overall.

Hackathons can be a great way to build camaraderie among your team members. The shared experience of working on a project as a group allows employees to work together and accomplish tasks they never thought possible. Additionally, the opportunity to interact with other teams in friendly competition helps generate excitement and establish positive relationships.

2. Great team building activity:

Hackathons give employees a fun and rewarding opportunity to get out of their comfort zone. It encourages people to work together towards a common goal while building on each other’s strengths and weaknesses. Employees can also learn new skills that they will be able to use in the future.

3. Employees are pushed out of their comfort zone:

Hackathons encourage employees to work together and build on each other’s strengths. It pushes people out of their comfort zone and allows them the opportunity to try something different.
Hackathons offer a low-risk, cost-effective way for you to promote creativity within your team.

Vibe Coding: Shaping the Future of Software

A New Era of Code

Vibe coding is a new method of using natural language prompts and AI tools to generate code. I have seen firsthand that this change makes software more accessible to everyone. In the past, being able to produce functional code was a strong advantage for developers. Today, when code is produced quickly through AI, the true value lies in designing, refining, and optimizing systems. Our role now goes beyond writing code; we must also ensure that our systems remain efficient and reliable.

From Machine Language to Natural Language

I recall the early days when every line of code was written manually. We progressed from machine language to high-level programming, and now we are beginning to interact with our tools using natural language. This development does not only increase speed but also changes how we approach problem solving. Product managers can now create working demos in hours instead of weeks, and founders have a clearer way of pitching their ideas with functional prototypes. It is important for us to rethink our role as developers and focus on architecture and system design rather than simply on typing code.

The Promise and the Pitfalls

I have experienced both sides of vibe coding. In cases where the goal was to build a quick prototype or a simple internal tool, AI-generated code provided impressive results. Teams have been able to test new ideas and validate concepts much faster. However, when it comes to more complex systems that require careful planning and attention to detail, the output from AI can be problematic. I have seen situations where AI produces large volumes of code that become difficult to manage without significant human intervention.

AI-powered coding tools like GitHub Copilot and AWS’s Q Developer have demonstrated significant productivity gains. For instance, at the National Australia Bank, it’s reported that half of the production code is generated by Q Developer, allowing developers to focus on higher-level problem-solving . Similarly, platforms like Lovable enable non-coders to build viable tech businesses using natural language prompts, contributing to a shift where AI-generated code reduces the need for large engineering teams. However, there are challenges. AI-generated code can sometimes be verbose or lack the architectural discipline required for complex systems. While AI can rapidly produce prototypes or simple utilities, building large-scale systems still necessitates experienced engineers to refine and optimize the code.

The Economic Impact

The democratization of code generation is altering the economic landscape of software development. As AI tools become more prevalent, the value of average coding skills may diminish, potentially affecting salaries for entry-level positions. Conversely, developers who excel in system design, architecture, and optimization are likely to see increased demand and compensation.
Seizing the Opportunity

Vibe coding is most beneficial in areas such as rapid prototyping and building simple applications or internal tools. It frees up valuable time that we can then invest in higher-level tasks such as system architecture, security, and user experience. When used in the right context, AI becomes a helpful partner that accelerates the development process without replacing the need for skilled engineers.

This is revolutionizing our craft, much like the shift from machine language to assembly to high-level languages did in the past. AI can churn out code at lightning speed, but remember, “Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” Use AI for rapid prototyping, but it’s your expertise that transforms raw output into robust, scalable software. By honing our skills in design and architecture, we ensure our work remains impactful and enduring. Let’s continue to learn, adapt, and build software that stands the test of time.

Guide to Conducting Successful System Design Interviews in 2025

What is Systems Design?

Systems Design is an all encompassing term which encapsulates both frontend and backend components harmonized to define the overall architecture of a product.

Designing robust and scalable systems requires a deep understanding of application, architecture and their underlying components like networks, data, interfaces and modules.

Systems Design, in its essence, is a blueprint of how software and applications should work to meet specific goals. The multi-dimensional nature of this discipline makes it open-ended – as there is no single one-size-fits-all solution to a system design problem.

What is a System Design Interview?

Conducting a System Design interview requires recruiters to take an unconventional approach and look beyond right or wrong answers. Recruiters should aim for evaluating a candidate’s ‘systemic thinking’ skills across three key aspects:

How they navigate technical complexity and navigate uncertainty
How they meet expectations of scale, security and speed
How they focus on the bigger picture without losing sight of details

This assessment of the end-to-end thought process and a holistic approach to problem-solving is what the interview should focus on.

What are some common topics for a System Design Interview

System design interview questions are free-form and exploratory in nature where there is no right or best answer to a specific problem statement. Here are some common questions:

How would you approach the design of a social media app or video app?

What are some ways to design a search engine or a ticketing system?

How would you design an API for a payment gateway?

What are some trade-offs and constraints you will consider while designing systems?

What is your rationale for taking a particular approach to problem solving?

Usually, interviewers base the questions depending on the organization, its goals, key competitors and a candidate’s experience level.

For senior roles, the questions tend to focus on assessing the computational thinking, decision making and reasoning ability of a candidate. For entry level job interviews, the questions are designed to test the hard skills required for building a system architecture.

The Difference between a System Design Interview and a Coding Interview

If a coding interview is like a map that takes you from point A to Z – a systems design interview is like a compass which gives you a sense of the right direction.

Here are three key difference between the two:

Coding challenges follow a linear interviewing experience i.e. candidates are given a problem and interaction with recruiters is limited. System design interviews are more lateral and conversational, requiring active participation from interviewers.

Coding interviews or challenges focus on evaluating the technical acumen of a candidate whereas systems design interviews are oriented to assess problem solving and interpersonal skills.

Coding interviews are based on a right/wrong approach with ideal answers to problem statements while a systems design interview focuses on assessing the thought process and the ability to reason from first principles.

How to Conduct an Effective System Design Interview

One common mistake recruiters make is that they approach a system design interview with the expectations and preparation of a typical coding interview.
Here is a four step framework technical recruiters can follow to ensure a seamless and productive interview experience:

Step 1: Understand the subject at hand

Develop an understanding of basics of system design and architecture
Familiarize yourself with commonly asked systems design interview questions
Read about system design case studies for popular applications
Structure the questions and problems by increasing magnitude of difficulty

Step 2: Prepare for the interview

Plan the extent of the topics and scope of discussion in advance
Clearly define the evaluation criteria and communicate expectations
Quantify constraints, inputs, boundaries and assumptions
Establish the broader context and a detailed scope of the exercise

Step 3: Stay actively involved

Ask follow-up questions to challenge a solution
Probe candidates to gauge real-time logical reasoning skills
Make it a conversation and take notes of important pointers and outcomes
Guide candidates with hints and suggestions to steer them in the right direction

Step 4: Be a collaborator

Encourage candidates to explore and consider alternative solutions
Work with the candidate to drill the problem into smaller tasks
Provide context and supporting details to help candidates stay on track
Ask follow-up questions to learn about the candidate’s experience

Technical recruiters and hiring managers should aim for providing an environment of positive reinforcement, actionable feedback and encouragement to candidates.

How Candidates Use Technology to Cheat in Online Technical Assessments

Impact of Online Assessments in Technical Hiring

In a digitally-native hiring landscape, online assessments have proven to be both a boon and a bane for recruiters and employers.

The ease and efficiency of virtual interviews, take home programming tests and remote coding challenges is transformative. Around 82% of companies use pre-employment assessments as reliable indicators of a candidate's skills and potential.

Online skill assessment tests have been proven to streamline technical hiring and enable recruiters to significantly reduce the time and cost to identify and hire top talent.

In the realm of online assessments, remote assessments have transformed the hiring landscape, boosting the speed and efficiency of screening and evaluating talent. On the flip side, candidates have learned how to use creative methods and AI tools to cheat in tests.

As it turns out, technology that makes hiring easier for recruiters and managers - is also their Achilles' heel.

Cheating in Online Assessments is a High Stakes Problem

With the proliferation of AI in recruitment, the conversation around cheating has come to the forefront, putting recruiters and hiring managers in a bit of a flux.

According to research, nearly 30 to 50 percent of candidates cheat in online assessments for entry level jobs. Even 10% of senior candidates have been reportedly caught cheating.

The problem becomes twofold - if finding the right talent can be a competitive advantage, the consequences of hiring the wrong one can be equally damaging and counter-productive.

As per Forbes, a wrong hire can cost a company around 30% of an employee's salary - not to mention, loss of precious productive hours and morale disruption.

The question that arises is - "Can organizations continue to leverage AI-driven tools for online assessments without compromising on the integrity of their hiring process? "

This article will discuss the common methods candidates use to outsmart online assessments. We will also dive deep into actionable steps that you can take to prevent cheating while delivering a positive candidate experience.

Common Cheating Tactics and How You Can Combat Them

Using ChatGPT and other AI tools to write code
Copy-pasting code using AI-based platforms and online code generators is one of common cheat codes in candidates' books. For tackling technical assessments, candidates conveniently use readily available tools like ChatGPT and GitHub. Using these tools, candidates can easily generate solutions to solve common programming challenges such as:
- Debugging code
- Optimizing existing code
- Writing problem-specific code from scratch
Ways to prevent it
- Enable full-screen mode
- Disable copy-and-paste functionality
- Restrict tab switching outside of code editors
- Use AI to detect code that has been copied and pasted
Enlist external help to complete the assessment

Candidates often seek out someone else to take the assessment on their behalf. In many cases, they also use screen sharing and remote collaboration tools for real-time assistance.

In extreme cases, some candidates might have an off-camera individual present in the same environment for help.

Ways to prevent it
- Verify a candidate using video authentication
- Restrict test access from specific IP addresses
- Use online proctoring by taking snapshots of the candidate periodically
- Use a 360 degree environment scan to ensure no unauthorized individual is present
Using multiple devices at the same time

Candidates attempting to cheat often rely on secondary devices such as a computer, tablet, notebook or a mobile phone hidden from the line of sight of their webcam.

By using multiple devices, candidates can look up information, search for solutions or simply augment their answers.

Ways to prevent it
- Track mouse exit count to detect irregularities
- Detect when a new device or peripheral is connected
- Use network monitoring and scanning to detect any smart devices in proximity
- Conduct a virtual whiteboard interview to monitor movements and gestures
Using remote desktop software and virtual machines

Tech-savvy candidates go to great lengths to cheat. Using virtual machines, candidates can search for answers using a secondary OS while their primary OS is being monitored.

Remote desktop software is another cheating technique which lets candidates give access to a third-person, allowing them to control their device.

With remote desktops, candidates can screen share the test window and use external help.

Ways to prevent it
- Restrict access to virtual machines
- AI-based proctoring for identifying malicious keystrokes
- Use smart browsers to block candidates from using VMs
