Questions I think you must be able to answer From your resume: Explain JWT Authentication end-to-end. Explain Socket.io architecture. Explain Redux store and reducers. Explain MongoDB schema design for Pinterest clone. Explain Razorpay payment flow. Difference between let, const, and var. Promise vs async/await. Event Loop in JavaScript. REST API status codes. What happens when you type a URL in the browser? My assessment Your projects are stronger than many fresher resumes. The biggest risk is not DSA—it is whether you can explain your own projects deeply. CarDekho interviewers are known to go deep into project discussions. If you built those projects yourself and can explain every major feature, your chances improve significantly. For this specific role, I'd spend: 50% preparation on MERN concepts 30% on your projects 20% on DSA (arrays, strings, recursion, hashing, DFS) If you get the task round, send me the task description and I'll help you prepare a solution approach before
