I recently appeared for a developer interview that mainly focused on JavaScript fundamentals, Node.js, Express, and databases (MySQL & MongoDB).
The overall experience was smooth and focused more on understanding the core concepts than tricky puzzles. If you're clear with JavaScript basics, comfortable building simple REST APIs, and understand how relational and NoSQL databases work, you'll do great!
Interview questions [1]
Question 1
How would you handle errors in an Express API, especially in async routes?
