I'm gearing up for a whiteboard interview with a technical team focused on a product that involves JavaScript, Node, and React. I've already completed a behavioral interview and an online coding assessment, and I know there will be cultural fit interviews later. Since this role leans more into frontend work, I want to effectively narrow my preparation.
How should I approach my preparation for the whiteboard interview? Should I dive into Node concepts like the event loop and non-blocking architecture, or focus more on JavaScript and things like API calls? Additionally, I could emphasize React—are there specific hooks or third-party libraries like Express or MobX I should know about? Is it worth practicing LeetCode problems in general? And if I need clarity, is it okay to reach out to HR for more information about what to expect? Anyone here experienced with whiteboard interviews for a MERN stack or similar? I'd love to hear your stories!

You might want to reach out to the hiring manager for more details about the interview format. They can tell you whether it will focus on data structures, algorithms, or possibly system design. The more you know, the better you can prepare!
Whiteboard interviews are less about getting perfect syntax and more about demonstrating your thought process and communication skills. Use pseudocode where necessary. Focus on understanding concepts at a high level instead of sticking strictly to problems from sites like LeetCode. Tailor your preparation based on the job requirements and what the interviewer is looking for—don't hesitate to ask them questions during the interview!
Thanks for the tip! It's useful to know that the focus is more on communication.
That sounds like a good idea! I had a phone screen too and didn't think to ask. It can't hurt to ask HR; they may appreciate your initiative.
