Programming Aptitude Test: A Quality Way to Hire

Introduction

Society for Human Resource Management states employers spend an average of US$4,129 on every job hiring in the United States. Despite spending considerable resources, financial and otherwise, companies are unable to find quality talent. Organizations often agreed on hiring the best talent at the time but realized they were either underskilled or unprepared to work within a functional environment. The struggle is real because irrespective of the changes in hiring strategies, most practices remain the same, such as an incomplete or inefficient assessment of a programmer’s aptitude.

Let’s take an example:

 The campus hiring season has begun. Companies are receiving a large number of applications and have a significant talent pool from which to choose. With a significant number of candidates having similar qualifications, companies often shortlist swiftly, rather than analyzing the candidate’s abilities to learn and realizing their application of the skills necessary for being a successful programmer. The result is multiple screening and interviewing without favorable outcomes. Two other factors also hinder the hiring efficiency – one is asking non-technical recruiters to assess and filter engineers. The other is candidates exaggerating their abilities and proficiency during interviews to create a favorable impression. When recruiters hire in bulk, they find it challenging and time-consuming to validate such claims, and eventually face challenges. 

If this is a common phenomenon at your hiring drives, you must shift to a new candidate assessment approach that can address pain-points and exceed the hiring manager’s and the company’s expectations. It can be made possible by understanding the coder’s programming aptitude. When you’re scaling development teams and maximizing agility, assessing a fresher’s coding aptitude is critical. As proficient coders are not just known for their existing skills but also for their ability to learn and perform better in the future.

What is Programming Aptitude?

A ‘Programming Aptitude’ involves a comprehensive evaluation of a fresher before undertaking a hiring decision. When hiring in bulk, programming aptitude is a useful filter that distinguishes great coders from the mediocre ones. It showcases the level of clarity on the fundamentals and predicts their potential for learning and development.

The measurement of aptitude is necessary because assessing coders is an extremely complex process involving various factors. It transcends their past engagements while considering the future potential. Hence, a recruiter may find it challenging to assess candidates based on sizable parameters, merely screening obviously deserving ones. Thus, a programming aptitude test offers them significant insights into the candidate’s capabilities.

Organizations are inclined toward programming aptitude testing to improve their recruitment and development processes and avoid high job turnover rates. They substantially reduce errors in predicting employee performance with their structured approach as organizations can identify exemplary candidates and remain informed about the valuable contributions each one brings to their business.

How to Measure Programming Aptitude

When scouting for a small group of quality candidates from a mass pool, a programming aptitude test measures a series of core skills, such as job seekers’ technical knowledge and comprehension. 

They include:

Programming Aptitude also measures a fresher’s focus and effort level, psychological adeptness in handling large projects, programming language design, team formation, the programming environment, potential success and much more.

A Programming Aptitude Test Solution

A Programming aptitude test gives you an understanding of a programmer’s capability to learn and comprehend and provides insights into the extent of knowledge they can apply and analyze. 

It provides a combination of customizable MCQ’s and simulators focusing on:

  • Decoding a candidate’s coding aptitude and the ability to build an efficient code
  • A candidate’s understanding of core technical concepts on a diverse set of technologies
  • A candidate’s coding proficiency in general programming languages

Here Are Six Simple Steps To Test Coders’ Programming Aptitude:

  • Create an MCQ test to find core technical concepts. Questions should be based on essential knowledge, concepts, applications, and analyses of a diverse set of technologies.
  • Filter out candidates that meet your essential coding criteria.
  • Analyze the shortlisted coders’ problem-solving skills by asking them to perform real-world tasks or solving test cases using coding simulators. This tests candidates’ coding proficiency in general programming languages.
  • Further, filter the candidates for the interviews based on detailed automated reports that thoroughly evaluate their coding aptitude.
  • Validate the resume and find hidden skills via online interviews. A live coding analysis on the interview platform enables recruiters to get the real picture of the candidates’ abilities and accomplishments.
  • Make an evidence-based decision and improve your hiring quality.

How Do MCQ’s and Simulators Help in Testing the Programming Aptitude?

MCQs and Simulators, together, filter and screen fresh campus talent at scale to help understand the core competency of a candidate and help hire the best potential talent to take on a variety of coding tasks in the future. 

  • Multiple Choice Questions (MCQ’s) are one of the most useful question types to gauge the candidate’s learning. They are not merely simple go-to questions. They extensively cover the topic or skill. Hence when framed, the focus is on higher and future levels of thinking. This process offers a quick and precise evaluation over a tremendous scope of the content. 
  • The best way to analyze coders’ skills is by making them code and evaluate several parameters: code quality, efficiency, correctness, and scalability of the code. Coding simulators are undertaken on a platform to get a real sense of candidates’ ability and approach toward real projects with real-world challenges. Candidates create code from scratch; they are auto-graded in no time, which provides direct insight into their coding aptitude and on-the-job potential.

Conclusion:

There is no need to persist with traditional, non-functional methods. Tech recruitment is evolving, and so is the process of screening and interviewing candidates at scale. When organizations invest significant effort to hire the right candidate, they also have to apply adequate filters that rest their imprecise shortlisting and inefficient assessment. There needs to be a more focussed approach to ensure every hired professional brings certain value to the company rather than merely filling up a vacancy. Companies need to realize that hiring has some specific goals that must be accomplished. And by hiring generalized engineers, they are jeopardizing the present and the future goals. 

Even at the entry-level, proficient coders should have a solid foundation of technical skills, even in one programming language. They should also have the potential to adapt either by upskilling or reskilling as new demands emerge. However, to accomplish this, companies have to look beyond the merits and instead of the actual ability to code. One can only determine such characteristics by undertaking a programming aptitude test of various candidates. It is a fundamental futuristic evaluation criterion.

How Mercer | Mettl Can Help?

Plagiarism Checker

With a significant number of candidates taking the assessment, there is a high probability of at least two similar codes arising. Our coding simulator identifies candidates' submissions and detects if they are similar, partially, for better decisions. We use MOSS (Measure of Software Similarity) and a string comparison algorithm to check plagiarism. Usually, we prefer MOSS for more extended codes (with relatively more number of lines). Our checker is also competent at detecting copied codes from the internet.

Remote Proctoring

Whether enabling human proctoring or deterring students' attempts at cheating by employing high-tech and innovative means, a comprehensive suite of anti-cheating solutions and a robust invigilation mechanism continually supervises students.

Auto-Suggest Logic (Intellisense)

Our online coding simulators feature ‘Intellisense.’ It is an auto-complete feature that automatically recommends language-specific, context-driven suggestions at specific syntax points. It can be activated if required.

Code Playback

Have you ever thought of watching a movie to evaluate a candidate's code? We share the full video of code, recorded at each keystroke, to help you analyze the candidates’ thought process behind their execution. It is integrated closely with code editors, such as Emacs, Vims and Sublime. Code Playback shows you the video of the code’s evolution at each compilation. It is another way to evaluate on-the-spot proficiency and the capability to code in the desired language.

Custom Scoring and Report

Apart from knowing how to code, measuring other parameters, such as the code’s perfection, correctness, difficulty level, time and space complexities, and other such vital measures, is possible with custom-scoring. Companies can easily award points to each of the hidden and default test cases, which are successfully passed on several parameters. The candidate is then given a score based on the parameters, considered the benchmark for getting to the next level. Generating a customized report, extracting every minute detail of the coder that helps scrutinize and understand them better, is also possible.
