Overview
HackerRank Interviews are designed to help you conduct specific coding and technical skills assessments of candidates. These assessments primarily include coding questions of varying complexity in different programming languages and diverse frameworks. However, interviewers can also have subjective and diagram questions to assess a candidate's knowledge in particular subjects depending on the job requirements.
This article provides an overview of the different question types supported by HackerRank Interviews.
Supported Question Types
| Question Type | Overview |
|---|---|
| Coding |
Questions for which you write programs or define logic in functions to produce the expected output. Coding questions may have varying complexity levels and can be designed to allow coding in particular programming languages. An in-built code editor and compiler adapt itself to a chosen language, and test cases validate your code to produce the expected output. |
| Front-end developer |
Questions on front-end web application development using frameworks such as Angular, React.JS, Node.JS, or other custom frameworks. You are provided with a front-end project and access to an IDE where you can run and test your code in offline or online modes. |
| HTML/CSS/JavaScript programming | Questions to assess web page designing skills using HTML, CSS, and JavaScript code. You are expected to design and structure web pages, and with the click of a button, you can view how your code renders in a web browser. |
| Back-end developer |
Questions on back-end web application development using frameworks such as Node.js, Django, Ruby on Rails, Java Spring Boot, or other custom frameworks. You are provided with a back-end project and access to an IDE to run and test your code in offline or online modes. |
| Database Engineer |
Database programming Questions based on MySQL, Oracle, Microsoft SQL, or DB2. You are expected to write database queries pertaining to data storage, retrieval, and management. Typically, the test setter defines the data schema along with the problem statement. |
| Diagram | Questions that you answer with class diagrams, structure diagrams, flowcharts, or architectural diagrams. The test interface provides the integrated draw.io tool to help you create these diagrams. |
| Data science |
Questions to assess skills like data wrangling, visualization, machine learning, etc through Jupyter Notebooks. (Optional) You can use additional files to upload external files like data sets or scripts. You can add solution notebooks or evaluation files. These files are not available to the candidate during a test and will be used after the test to score a candidate's submission. |
| Full-stack developer |
Questions on full-stack web application development using frameworks such as Angular, React.JS, Node.JS, Django, Ruby on Rails, Java Spring Boot, .Net Core, or other custom frameworks. You are provided with a back-end project and access to an IDE to run and test your code in offline or online modes. This question type supports both front-end and back-end developer frameworks in a single question type. |
| DevOps |
Questions to assess the Linux skills of a candidate. You are provided with an integrated shell terminal on a Linux server to work on bare machines or predefined tasks. |
| Mobile Development |
Questions to assess the mobile development skills of a candidate. A built-in emulator is provided inside the IDE for the interviewers and candidates to build and see their code in real-time. |
| Whiteboard | Questions where you can use the whiteboard to add basic shapes and text. |
| Code Review |
Interviewers can now use Code Review questions in Interviews to assess candidates on their coding skills. In Code Review questions, Interviewers can share code written by someone else and ask the candidates to provide suggestions and comments to improve the code. |
