A3logics NodeJs interview questions

The first stage is usually the coding or technical screening round, where the main goal is to evaluate your problem-solving ability and logical thinking. Interviewers want to see how you approach a problem, not just whether you reach the correct answer. Questions are commonly based on Data Structures and Algorithms such as arrays, strings, searching, sorting, stacks, recursion, and basic logic building. You may be asked to reverse an array, find the second largest element, check for a palindrome, or solve a simple logic-based problem. During this round, they observe how you understand the question, whether you explain your approach before coding, how you handle edge cases, and whether you try to optimize your solution. Clear thinking and structured explanation matter more than speed.
