Nykaa Interview Experience | SDET (QA Automation) | 2 Rounds | DSA + SQL + API Testing

Recently, I appeared for the interview process at Nykaa for the SDET (Software Development Engineer in Test – QA Automation) role.

The interview process covered DSA, SQL, HTTP fundamentals, API testing, and project-based discussions around Agentic AI.

Sharing my experience to help other candidates preparing for similar roles.

Round 1 – Technical Interview

The first round focused on problem-solving, SQL, HTTP fundamentals, and API testing.

1. DSA Questions

Q1. Remove Duplicates from Sorted Array

• Remove duplicates from a sorted array in-place.
