HackerRank Interview Interface
The interface has a built-in code editor that supports various programming languages. The live video-chat option allows you to engage and interact with your interviewers using chat, video, and call options.
Note: The chat window and audio and video calls are supported by Firefox, Google Chrome, Safari, and Microsoft Edge browsers.
Tip: You can move the chat window wherever you want on the Interview screen.
Your interviewer posts different questions to you during the Interview, and each question is displayed in a separate Question tab. (Upper left of the screenshot below) When you are viewing a particular Question tab, click the Task Description pane on the left to view the complete problem statement. You must read and comprehend the problem statement carefully before answering the question.
The Languages option lists the programming languages permitted by your test setter to answer a particular question. Typically, based on the specific skills the company wants to assess in a Candidate. The test setter determines the languages which will be available for coding. You must choose from the available programming languages to code your solution, and Interview's code editor automatically switches and adapts itself to the chosen language.
The lower half of the code editor displays the sample input values, compilation status, and output from your code.
The Input tab displays the input values from the Sample Test cases if they are defined in the Question. Sample input values may be included in a coding Question to help you understand the type of input passed by the test cases to your code and the expected output values from your solution. To test your code, click "Run Code". The output produced by your solution or any compilation errors and warning messages is displayed in the Output area.
Click the "Run all test cases" option to execute all the test cases covering edge scenarios for the solution. The output is shown in the Output tab, as shown below.
