For React interviews, here are some of the most common questions that I encounter and thought it to be worth sharing. 1. Output questions - These are loved by all the companies, they test the thinking and conceptual knowledge of the candidate, and most of the topics I faced them were from event loops, setTimeout, closures and this keyword. 2. Closures - The second most favorite topic of the interviewers, these are mostly asked along with their output questions. 3. Polyfills - Writing the basic utility functions from scratch test your knowledge for how well you write the code and logics. Most common questions include debounce and throttle polyfills along with filter,map and reduce. 4. Explaining projects - Your projects depict the work and skills you have which are equally important for any company. Make sure to keep in mind your most difficult challenges so that when they come up in an interview, you are prepared to communicate to them. 5. Async/Await and Event Loops - Understanding how the call stack, microtask queue, and macrotask queue work is very important. Many questions revolve around predicting the output when Promise, setTimeout and async/await are involved.

Interviews have been teaching me something lately, Sometimes knowing how something works is not the same as explaining it cleanly. This week I am spending time on tightening how I talk about React concepts. Things like component lifecycle behavior, hooks and error handling. I realized that understanding is not enough and in an interview setting concepts like this should be so familiar that explaining them feel natural and can easily be brought up without struggling, even under pressure. #React #FrontendDevelopment #SoftwareEngineering #WebDevelopment #JobSearch #ContinuousLearning #TechCareers #CareerGrowth #ReactJS #LearningJourney
