What is technical screening?

Technical screening is the process of testing a candidate’s technical skills and problem-solving abilities during hiring. This screening helps recruiters ensure that candidates hold the required technical skills outlined in the job description.

It is a rigorous process that must provide an unbiased and reliable assessment of coding skills, IT security knowledge, programming abilities, problem-solving approach, and other essential qualifications for the job.

Typically, the hiring process involves several stages for candidates to complete. Most of the time, the technical screening process is conducted early on, followed by cultural fit interviews for further shortlisting.

Technical screening can include a structured test or a real-time interview, where candidates have the opportunity to demonstrate their skills on the spot. This allows a fair and accurate evaluation.

Technical interview vs Technical screening

While hiring for tech positions, both technical interviews and technical screenings play essential roles, but they serve different purposes throughout the hiring process.

Think of technical screening as a filter designed to quickly identify candidates who meet the basic technical requirements for the role. The process is generally automated, utilizing assessments such as coding tests that score candidates quantitatively. It’s a straightforward way to evaluate technical knowledge.

Technical interviews, on the other hand, dig much more deeply. Technical interviews are more interactive and personal, often involving live coding exercises, system design challenges, and discussions around real-world scenarios.

These interviews allow candidates to showcase their thought processes, creativity, and approach to complex challenges. As a result, they are usually reserved for later stages of the hiring process.

In some hiring processes, there can be an overlap between the two. For example, a technical interview might include elements of a technical screen, such as a coding challenge, as part of a broader conversation.

The combination of technical screenings and technical interviews offers a balanced and thorough evaluation process. Below is a table to help clarify the differences between technical interviews and screenings.

Technical Screening	Technical Interview
Filters out candidates who lack basic technical skills early in the hiring process.	Provides an in-depth assessment of a candidate’s technical abilities and cultural fit.
Tests broad technical knowledge (e.g., programming languages, tools, frameworks).	Focuses on practical expertise, problem-solving skills, and real-world application.
Often automated with coding tests, quizzes, or multiple-choice questions.	Involves interactive methods like live coding, whiteboarding, and in-depth discussions.
Conducted early to filter the candidate pool quickly.	Takes place later, after the initial screening stages have been completed.
Quantitative scoring to assess whether a candidate meets minimum skill requirements.	Qualitative evaluation, assessing depth of understanding and communication skills.
Typically quicker and less time-consuming for both candidates and recruiters.	More time-intensive, requiring one-on-one interaction with candidates.
Can be fully automated using testing platforms for quick evaluations.	Requires manual effort from interviewers, making it a more personalized experience.
More structured and less personalized, but it offers flexibility to complete remotely.	Provides a chance for candidates to showcase their thought process and ask questions.
Helps eliminate unqualified candidates early, saving time and resources.	Crucial in making the final hiring decision, offering a deeper insight into the candidate.
Ideal for high-volume hiring where many candidates need initial evaluation.	Best for roles where in-depth technical and cultural fit are critical.

Importance of technical screening in hiring

Ever wondered why technical screening is such a game-changer in hiring? 

A resume might highlight impressive experience, but how can you be sure a candidate truly has the skills they claim?

That’s where technical screening comes in, acting as a reliable tool for recruiters and HR to verify candidates’ expertise.

Let’s dive into why this step is so crucial, especially when you’re on the hunt for top tech talent.

1. Validates skills beyond the resume

A resume provides a glimpse into a candidate’s experiences and professed skills, but technical screening takes things a step further by verifying those claims. 

The screening process clarifies whether a candidate genuinely possesses the technical skills they’ve listed. This validation process helps avoid hiring based solely on resume embellishments and guarantees that the skills on paper translate to real-world abilities.

2. Improves efficiency in the hiring process

Time is often the biggest challenge in tech recruitment. Technical screening serves as an initial filter, allowing recruiters to focus their efforts on qualified candidates from the start.

When you filter out candidates who don’t meet the baseline skill requirements, it can significantly reduce the number of interviews. 

This way, HR and hiring managers can spend more time with candidates who are genuinely a good fit rather than those who fall short technically.

3. Reduces unconscious bias

Unconscious biases, such as the halo effect or intuition bias, can influence hiring decisions, often without recruiters even realizing it.

Technical screening helps counter this by offering a standardized, objective evaluation of candidates’ skills.

Since many assessments are automated or follow a strict scoring system, they ensure that every candidate is judged on their technical merits rather than on personal impressions.

4. Enhances the candidate experience

A positive candidate experience is crucial for attracting top talent. Technical screening plays a key role in this by providing candidates with an opportunity to demonstrate their skills in a structured manner.

Candidates can complete various assessments remotely at their convenience, making the process less stressful and more flexible.

Moreover, when candidates receive meaningful feedback on their performance, such as scores or constructive feedback, they feel respected and valued, even if they don’t make it to the next round.

5. Boosts the quality of hires

Technical screening is not just about filtering out unqualified candidates; it’s also about identifying those with the most substantial potential. It ensures that candidates who advance to later stages are those who can truly excel in the role.

6. Identifies gaps for future development

Sometimes, you may come across candidates who are a great cultural fit and have most of the skills you’re looking for, but fall short in one or two areas. 

Technical screenings can highlight these gaps, allowing you to determine whether you’re willing to invest in their training and development after hire.

7. Reduces hiring costs significantly

Hiring errors are expensive. According to Glassdoor, the average cost-per-hire for a tech position exceeds $4,000, and IT roles often take about 44 days to fill (LinkedIn Hiring Report, 2023). 

Technical screening drastically reduces these expenses by filtering out unsuitable candidates upfront.

By minimizing the time spent on unsuitable candidates, you can significantly cut down on costs and make more efficient use of resources. It’s a win-win for both the company and the candidates.

How to conduct a technical screening?

Hiring the right tech talent can feel like searching for a needle in a haystack. But with a solid technical screening process, you can quickly find those needles without sifting through endless resumes.

Let’s review a practical guide for conducting a technical screening that’s both efficient and engaging.

Step-by-step process

1. Define clear and relevant job criteria

Clearly outline the essential skills and frameworks required for the role. Engage directly with hiring managers to ensure you’re aligned on non-negotiables. This groundwork sets the stage for accurate assessments and reduces mismatches early on.

Meet with the hiring manager to create a list of must-have skills and translate that list into your job description.

Start with a broad technical screening to filter out candidates who meet your basic criteria. As the pool narrows, you can customize the following steps to dive deeper into their expertise.

For highly specialized positions, follow up with technical interviews or pair programming exercises, which can give you a closer look at how candidates solve problems in real-time.

2. Start with automated assessments

Most companies begin with pre-interview online assessments to evaluate a candidate’s baseline technical skills. These could be timed coding challenges or multiple-choice tests that take less than an hour. 

It’s a quick way to narrow down the candidate pool and focus on those who meet the basic technical requirements.

Platforms like Testlify make this process seamless, providing automated scoring and analytics. This way, candidates can take the tests at their convenience while you get the results instantly.

3. Phone interview/screening for a personal touch

Once candidates pass the initial assessment, a phone screening is a great way to get to know them beyond their test scores. Here, you can ask general background questions about their experience, education, and projects.

If needed, you can also include a practical element by asking candidates to solve a simple problem in a shared editor or Google Doc. This helps you evaluate their thought process and communication style without the need for a full-blown technical interview.

Types of assessments

1. Pre-Interview online assessments: These serve as your first filter, designed to test core technical knowledge, including coding skills, algorithms, and problem-solving abilities.

2. Technical Interviews for deep insights: Technical interviews are where you dig deeper. These sessions go beyond what’s on the resume and assess practical knowledge and skills. For example, if you’re hiring a JavaScript developer, you might ask questions like:

• How do you handle exceptions in JavaScript?
• What are JavaScript’s common data types?
• What is a pure function?

In addition to technical questions, you might have candidates work through a coding problem live or present their approach to solving a specific challenge. It’s a way to see how they think and how they communicate their solutions.

3. Pair programming for real-time collaboration: Pair programming enables you to observe a candidate’s coding style, approach to problem-solving, and ability to adapt to feedback, all within a single session. Plus, it’s more interactive and engaging than traditional coding tests, making it a favorite among candidates.

One big advantage? It’s a faster way to zero in on top talent. After a successful pair programming session, you might only need one more round before making an offer. This saves time compared to multi-stage interviews.

Whether it’s through a coding test, a thoughtful technical interview, or a collaborative pair programming session, you’ll be able to uncover the talent that truly fits your team’s needs., or a collaborative pair programming session, you’ll be able to uncover the talent that truly fits your team’s needs.

Best practices for fair evaluation

1. Match the assessment to the role
2. Use standardized tests for consistency
3. Balance technical skills with real-world scenarios
4. Give feedback and create a positive experience
5. Combine automation with human insight

Challenges in technical screening and how to overcome them?

Let’s face it—technical screening can be a tricky process. It’s not just about finding the right candidate; it’s also about creating a fair and engaging experience for everyone involved. But don’t worry; every challenge has a solution.

Here’s a look at some common hurdles in technical screening and how you can tackle them head-on.

1. Achieving optimal balance between speed and quality

• The problem: Accelerating the hiring process without sacrificing candidate quality can be challenging. Indeed reports that 60% of recruiters feel pressured to make quick hiring decisions, leading to rushed decisions.

• How to overcome it: Use tools like Testlify or HackerRank to automate the first round of coding challenges. This way, you can quickly filter out those who don’t meet the basics. Follow it up with a quick technical interview or a pair programming session for top candidates. This combo keeps things moving without cutting corners.

2. Unconscious bias in evaluations

• The Problem: It’s easy for unconscious biases to sneak in during evaluations—maybe it’s the school a candidate went to, or how confidently they speak. But this can cause you to miss out on hidden gems who might think differently.

• How to Overcome It: Standardize your assessments and use automated scoring wherever possible. That way, everyone gets judged by the same criteria. Plus, training interviewers to recognize their own biases can make a big difference. Bringing in a diverse interview panel is another effective way to maintain balance and fairness.

3. Keeping candidates engaged

• The Problem: Let’s be honest—technical screenings can be nerve-wracking, especially if they’re long and dry. If candidates feel like they’re just jumping through hoops, they might lose interest and drop out.

• How to Overcome It: Make it fun and relevant! Keep assessments under an hour and ensure they reflect real-world tasks. Add an interactive twist, like a pair programming session, where they get a taste of your team’s work culture. And remember—candidates love feedback! Even a few pointers can make a huge difference in how they feel about the experience.

4. Finding the right difficulty level

• The Problem: If the tests are too easy, you end up with a lot of candidates who breeze through. Too hard, and you scare off great candidates who need a bit of guidance.

• How to Overcome It: Think of it like Goldilocks—you want the challenge to be just right. Collaborate with hiring managers to develop tests that accurately assess the role’s level. Mix it up with some easy, moderate, and a couple of tricky questions to see how candidates handle different scenarios. This way, you can spot those who can solve the basics and think outside the box.

5. Balancing technical skills with soft skills

• The Problem: Sure, you need someone who can code, but what about their communication skills or how they work in a team? It’s easy to miss out on these softer skills when you’re laser-focused on technical abilities.

• How to Overcome It: Combine technical tests with a bit of real-time interaction. Pair programming is perfect for this—you get to see how they explain their solutions, adapt to feedback, and work with others. It’s a great way to get a sense of their personality and determine if they’d fit into your team’s dynamic.

6. High drop-off rates

• The Problem: Sometimes, candidates just bail out in the middle of the process, especially if the assessment feels too long or disconnected from what they’d actually be doing on the job.

• How to Overcome It: Keep things transparent! Let candidates know what to expect and how long it’ll take. Use platforms that let them complete assessments at their own pace so they don’t feel rushed. And keep the focus on real, practical problems they’d face in the role—nobody wants to solve puzzles that don’t relate to the job.

7. Making sure your assessments are effective

• The Problem: How do you know if your test is really working? If your assessment is too easy, you might end up with false positives. Too hard, and you risk turning away great talent.

• How to Overcome It: Regularly review your tests and solicit feedback from current team members who have taken them. This helps ensure your questions are hitting the mark. Platforms with analytics can show you where candidates struggle, so you can tweak the questions and improve your process over time.

8. Challenge: Managing volume and maintaining consistency

• The problem: When you have hundreds of applicants, it’s tough to keep the process consistent. Different interviewers might evaluate differently, and that’s not fair to candidates.

• How to overcome it: Create a playbook! Standardize your process by establishing a set of core questions and a corresponding scoring rubric. Use digital tools that record results for transparency. This way, no matter who’s doing the interview, every candidate gets a fair shake.
