Resumes vs. Technical Screenings: The Hiring Conundrum in Engineering Jobs

In the rapidly evolving tech industry, hiring the best talent is more crucial than ever. With a sea of potential candidates, companies are continuously refining their hiring processes to identify the best fit for their teams. Two prevailing methods have emerged at the forefront of this movement: the traditional resume review and the modern technical screening, often through platforms like LeetCode. But which is more effective? In this article, we’ll dive deep into the merits and pitfalls of both, offering insights into which might be best suited for different scenarios.

1. The Resume: A Window into Experience

Resumes have been the cornerstone of the hiring process for decades. They offer a snapshot of a candidate’s professional journey, accomplishments, and qualifications.

Pros of Using Resumes:

  • Broad Overview: Resumes provide a comprehensive view of a candidate’s background. This includes their educational qualifications, work experience, projects, and even extracurriculars.
  • Track Record: They highlight a candidate’s progression, promotions, and longevity at a given company, often indicative of loyalty and growth.
  • Cultural Fit: Resumes can provide glimpses into a candidate’s interests and activities outside work, which can hint at a potential cultural fit with the organization.

Cons of Using Resumes:

  • Bias: Resumes can introduce unintentional biases. For instance, a hiring manager might favor candidates from particular schools or companies, leading to a less diverse candidate pool.
  • Not Always Reflective: A well-written resume does not necessarily equate to competency in a job. Some candidates might be excellent at marketing themselves on paper but may not have the depth of skills in reality.
  • Time Consuming: Sifting through hundreds or thousands of resumes is time-consuming and may not always yield the best results.

2. Technical Screenings: A Test of Skill

Technical screenings, especially through platforms like LeetCode, test candidates on their coding and problem-solving abilities.

Pros of Technical Screenings:

  • Objective Assessment: These screenings provide an objective measure of a candidate’s coding prowess, reducing biases associated with resumes.
  • Immediate Insights: Rather than relying on past accomplishments, technical assessments provide real-time insights into a candidate’s skills.
  • Standardized Evaluation: Since every candidate is given the same set of problems, comparisons become more straightforward.

Cons of Technical Screenings:

  • Narrow Focus: Platforms like LeetCode often emphasize algorithmic challenges, which may not always align with the actual job responsibilities.
  • Pressure-Induced Performance: Performing under the pressure of a timed assessment might not reflect a candidate’s real-world coding abilities, where they typically have more time and resources.
  • Potential for Memorization: Some candidates might “game” the system by memorizing solutions to common problems, thereby not truly reflecting their problem-solving skills.

The Ideal Approach: A Balanced Blend?

The decision between relying on resumes or technical screenings isn’t binary. Many companies now adopt a combination of both to maximize their chances of finding the right talent.

  1. Initial Screening with Resumes: Begin with a quick resume review to gauge a candidate’s experience and potential fit.
  2. Technical Assessment: Proceed to a technical challenge to assess coding skills objectively.
  3. Personalized Interviews: Based on results from both the resume and technical assessment, conduct in-depth interviews that not only dive into technical competencies but also soft skills, team fit, and cultural alignment.

By integrating both resumes and technical screenings into the hiring process, companies can enjoy the best of both worlds. They can capture a candidate’s comprehensive background and also objectively assess their technical aptitude.


While the debate between resumes and technical screenings is ongoing, it’s clear that both have their merits. The key for companies is to understand their specific needs and challenges, adjusting their hiring practices accordingly. As the tech industry continues to evolve, so will the strategies used to identify and hire top talent.
