Taking Front-end, Back-end, Full-stack Developer Assessments ♂
HackerRank's assessments for Front-end, Back-end, and Full-stack developer roles offer flexibility for solving project-type problems using either the HackerRank-provided VS Code IDE or a local, git-based IDE. For the best experience, we highly recommend using the HackerRank IDE.
Using the HackerRank IDE provides several benefits:
Access to Built-in Features: The HackerRank IDE includes tools like IntelliSense and other features tailored for coding assessments. These are designed to streamline the testing process by offering real-time feedback and code suggestions.
No Setup Required: The environment is pre-configured, so you don’t need to worry about dependencies or local configurations.
Seamless Integration: Your work is automatically saved, and submissions can be made without the hassle of managing local repositories.
Review theto ensure your environment is configured correctly.
Answering Project Assessments
Start the Test: Access the assessment via the "Start Test" button in your email invitation.
Read the Instructions: Carefully review the instructions and try a sample test to familiarize yourself with the platform.
Choose Your IDE: We recommend using the HackerRank IDE for ease. If you prefer using your local environment, ensure you meet all the software requirements.
Continue to Confirmation: Fill out the Confirmation Form with your details (name, email, years of experience).
Environment Setup: HackerRank will automatically configure the environment. Once setup is complete, click Go To Test to begin.
Answer the Questions: Click Solve to start answering role-based questions.
The setup process starts automatically once the question loads. If you exit during this process, you may need to install dependencies manually.
You can collapse the question pane to get more coding space within the IDE.
Run Code: Use the Run button in the menu to execute your code.
Test Cases: Click Run Tests to execute test cases against your code.
Running and Debugging Test Cases: Click Run Tests to execute the test cases against your code. You will need to use the terminal to debug your code, where you can review the status, output, and error logs for each test case. For questions that support a UI-based interface, you can view an enhanced layout showing individual test cases, their pass/fail status, and error logs directly. You can still refer to the terminal for detailed debugging and additional insights.
Preview the Application: You can preview your application by selecting Open Preview or clicking the Preview button in the top-right corner. Ensure pop-ups are allowed for real-time updates.
Terminal Access: Access the terminal from the menu when needed.
Avoid Modifying UI IDs: Do not alter the IDs or classes of existing UI elements, as they are essential for unit tests.
Auto-Save and Logout: If the test time elapses, you will be logged out, and your last auto-saved code will be used for evaluation.
Submit Code: Once satisfied with your solution, click Submit code. You can update submissions multiple times before the test ends.
Front-End Questions in HackerRank Interviews ♂
HackerRank Interviews contains Front-end frameworks, Angular and React.
Candidates can work on a highly responsive, stable, and familiar editor to solve the Front-end questions, without worrying about getting familiar with a new editor or platform disruptions during the interview session.
After you are logged into an interview as an interviewer, you can start the Front-end interview from the Interview landing page by clicking on the Front-end framework.
Select Angular or React frameworks to start an interview based on that framework.
The screen navigates to display three options to start a Front-end interview.
Select one of these three options:
Start from Scratch
Import Questions from Library
Import your own Project
HackerRank Interviews provides a simple project for you as a starting point in this option. You can modify the project before or during the interview to suit your needs.
Experience the new containerless VS Code IDE results in a faster loading and stable IDE that works with seamless unstable network connections. Developers can have faster and more accurate autocomplete when coding.
Built-In Real-time Preview
The IDE opens with a built-in preview window on the right pane. Any changes made by you or the candidate can be seen on the Preview tab.
As the IDE is containerless, you can view the preview in a browser. Click the browser icon to view the preview in a browser.
You can also select a responsive view (tablet, mobile, desktop, and so on) for the preview. Click the icon to view the responsive view.
Test Execution
You can run the test cases by clicking the Test tab. Click the Run Tests option. The output is displayed.
Built-in Dev Tools
The Dev Tools are available in the lower part of the Preview pane. You can clickfor the respective framework and launch the console.
The console works as a collaborative tool. The interviewer and the candidate can see their changes in real time.
Dependency Manager
On the left pane of the IDE, you can find the Dependencies search bar by clicking the cube icon.
External CSS and Javascript Support
The External Resources is present on the left pane. Enter the URL of the external CSS and JavaScript resources in the External Resources address to format and style the UI.
Other UI Enhancements
You can view the other enhancements in the UI that are based on the VS Code Editor in the following clip.
This option takes you to the Library section in the Interviews. Here you can select a question from HackerRank Library or a question created by your company inside HackerRank Library.
Click Use to launch the question along with the IDE. The IDE launches.
This option allows you to select your own starter code for interviews by uploading your own project zip file or adding it from a public Git URL. Save the project with an appropriate name to retrieve it in the subsequent interviews. After you import, the projects load in HackerRank’s Projects IDE.
Related questions
When seeking cybersecurity assistance, it's crucial to focus on legal and ethical solutions. Here's a breakdown of how to approach this responsibly:
1. Ethical Hackers vs. Illegal Activity
- Ethical Hackers (White/Gray Hat): These are certified professionals who perform penetration testing, vulnerability assessments, and cybersecurity audits with explicit permission. They operate under strict legal and ethical guidelines.
- Illegal Hacking Services: Avoid any service offering unauthorized access, data theft, or other illegal activities. These are criminal offenses and pose significant legal risks.
2. How to Find Legitimate Professionals (2023 Update)
- Certifications Matter: Look for experts with credentials like CEH (Certified Ethical Hacker), CISSP, or OSCP.
- Trusted Platforms:
- Bug Bounty Programs: Platforms like HackerOne or Bugcrowd connect organizations with vetted security researchers.
- Freelance Platforms: Upwork or Toptal list cybersecurity professionals with verified reviews.
- Cybersecurity Firms: Companies like CrowdStrike, Rapid7, or IBM X-Force offer enterprise-level services.
3. Red Flags to Avoid
- Services promising "100% undetectable" hacking.
- Requests for payment in cryptocurrency with no contract.
- Offers to hack social media, emails, or devices without proof of ownership.
4. If You Need Help in 2023
- Account Recovery: Contact platform support (e.g., Google, Facebook) directly.
- System Security: Hire a certified penetration tester via professional networks like LinkedIn or industry conferences (DEF CON, Black Hat).
5. Legal Consequences
- Engaging illegal hackers risks fines, data breaches, or criminal charges. Always ensure compliance with laws like the CFAA (Computer Fraud and Abuse Act).
Final Advice
For cybersecurity needs, prioritize transparency, contracts, and verified professionals. If you suspect a breach, report it to authorities like the FBI鈥檚 IC3 or your local cybercrime unit. Stay safe and lawful! 馃敀
