What Is HackerRank?

HackerRank is a coding-based technical skills and assessment platform that is used by more than 3,000 companies around the world. It provides a virtual environment for individuals to practice and improve their coding skills, solve programming challenges, and participate in coding competitions. HackerRank is widely used by companies, including technology and financial firms, to assess the coding and technical abilities of job candidates. The platform supports various programming languages, allowing users to choose the language they are most comfortable with. Additionally, it offers a range of challenges that cover different aspects of coding, algorithms, and data structures, making it a valuable tool for both learning and evaluating programming skills.


What to Expect on the HackerRank Test?

The HackerRank test incorporates three question types: Multiple Choice Questions (MCQs), Coding Exercises, and SudoRank Exercises. MCQs delve into topics like time complexity, presented in a multiple-choice format, while Coding Exercises require candidates to solve programming problems with defined input and output formats. SudoRank Exercises involve fixing issues on a server accessed via SSH. Companies may combine these questions and often provide insights into the test content. The number of questions varies and is categorized by difficulty levels, such as easy, medium, and hard. The exam requires coding challenges where candidates tackle specific problems within a time frame, typically ranging from 30 minutes to a few hours, but the duration is approximately 60 minutes for the math assessment and 120 minutes for programming/coding. It is advisable to allocate extra time for preparation.

Candidates use a real-time coding environment, selecting from supported programming languages. Topics include algorithms and data structures tailored to assess skills relevant to the job. The automated evaluation system checks code correctness and efficiency, yielding a score based on accuracy and runtime efficiency. Candidates can choose from programming languages such as C, C++, Java 7, Java 8, JavaScript, Python 2 & 3, or Scala for the assessment.


HackerRank’s Interviews

HackerRank Interviews is a tool for conducting technical interviews online. If a candidate does well in the initial assessments, they may have an interview using this platform. It’s a flexible and efficient way to evaluate candidates remotely. The key features include access to a library of questions for interviewers to choose from, the ability for all participants to edit and test code together, built-in chat for communication, a playback feature to review the entire interview, guidelines for interviewers, and a built-in coding environment that supports over 40 programming languages. Interviews are dynamic, allowing interviewers to adjust questions based on a candidate’s progress. Overall, it’s a convenient and cost-effective method for real-time assessment.


Companies That Use the HackerRank Assessment

Many companies across various industries use HackerRank as part of their recruitment and assessment processes. Here are some well-known companies that use it:

Goldman Sachs Crossover Quora SoFi Facebook Adobe AMD
Harman International Microsoft Cisco Nvidia
Qualcomm Dropbox Uber Amazon
MediaTek Broadcom


How to Prepare for the HackerRank Test?

For HackerRank preparation, applicants are encouraged to familiarize themselves with the platform by taking a sample test. Practice can include reviewing algorithms and basic data structures and, for those opting for the math assessment, revisiting calculus, statistics, linear algebra, and probability concepts.

HackerRank offers a library of questions, and companies can also create their own. Strategies for tackling questions include using Google for multiple-choice queries and searching for exercise titles to find related solutions. The article discusses potential pitfalls, such as candidates finding answers online. Additionally, it highlights recruiter insights, suggesting that some recruiters may share test details with candidates, influencing performance statistics. The piece concludes with a challenge related to a trading algorithm coding exercise.

Feedback on the HackerRank assessment is evaluated alongside other application materials, and candidates can expect an update from the campus recruiting team within three weeks. Real-time application status updates are available on the candidate portal.

HackerRank strives to move away from traditional, resume-based hiring in favor of skills-based hiring. Overall, it is widely embraced by companies as an efficient and standardized tool for evaluating coding and problem-solving skills in job candidates.
