Can I use Internet during coding interview?

During most formal coding interviews, especially those conducted by companies as part of the hiring process, the use of the internet is typically restricted to specific tasks. Here’s how it generally breaks down:

1. Code Execution and Environment Setup

• Online IDEs: Many companies use online coding platforms like CoderPad, HackerRank, or CodeSignal for conducting interviews. These platforms often allow you to run your code to test it, but they don't usually allow browsing the internet for solutions or documentation.
• Specific Documentation Access: In some cases, you might be allowed to access official documentation for specific programming languages or APIs. This is more common in interviews that focus on practical skills and real-world tasks, such as those for web development roles.

2. General Internet Use

• Looking Up Syntax: Some companies allow you to look up language-specific syntax if you are stuck. This can be particularly true in cases where the interview is language-agnostic and the focus is more on solving the problem than on language mastery.
• Using Standard Libraries: Accessing documentation for standard libraries is often permitted because it's part of effective coding practices. However, this usually doesn’t extend to broader internet searches or solution hunting.

3. Restrictions

• No Solution Searching: Searching for solutions to the specific problem you are being asked to solve during an interview is generally not allowed. This includes looking up similar problems on sites like Stack Overflow, GitHub, or even searching through public code repositories.
• No External Communication: You are not allowed to communicate with others for help during a coding interview. This includes any form of messaging or posting on forums.

4. Best Practices

• Clarify Rules with Interviewer: At the beginning of the interview, it's a good idea to ask what resources are permitted. This can vary by company and even by interviewer.
• Prepare Accordingly: Since internet access is generally restricted, it’s best to prepare by practicing coding without relying on the internet to look up information or solutions. This helps ensure you are ready for the typical conditions of a coding interview.
• Focus on Problem-Solving Skills: Use the interview as an opportunity to showcase your problem-solving abilities and your familiarity with coding principles and patterns, rather than relying on searching for answers.

5. Ethical Considerations

• Honesty: If you find yourself in a situation where you don’t know the answer, it’s better to be honest with the interviewer about your gaps in knowledge rather than trying to covertly find answers online. Discussing how you would approach finding the solution can also be insightful for interviewers.

Conclusion

Generally, the use of the internet during coding interviews is restricted to ensure that the skills assessed are your own. Preparation for interviews should, therefore, focus on building a strong foundation in coding and problem-solving skills to navigate these constraints effectively. Always clarify the specific rules with your interviewer or the hiring company beforehand to avoid any misunderstandings.
