Sdet Interview Questions

4,403 sdet interview questions shared by candidates

Round one had two coding questions, one was based on hashmaps and matrices (30 minutes), and the other was about combinations (20 minutes). Both were not too difficult, but the time constraint was a problem. They were scenario based questions. There also were technical aptitude questions and quants, about 25 of them in total. Since they had negative marking, I did not attend a few questions, and was able to pass 3 test cases in the 20 minute question, and was able to complete the other question. Got selected to the next round, which was the technical interview. Questions were: Boundary traversal of a tree, Kth last node in a Linked list, Searching in a sorted, rotated array, heaps, and a bit about my projects on my resume. Didn't do well in this round because I panicked. But it was average overall. They expect you to know a lot beyond your curriculum.

1. Technical Interview (1.5 hours): This round was highly detailed and began with core Java concepts, including OOP principles, the Collections Framework, and exception handling. It also included three DSA questions, all array-based, focusing on problem-solving and optimization. Additionally, I was asked SQL queries ranging from basic to intermediate difficulty and had to explain my final year project and other projects mentioned in my resume. The interviewer asked in-depth questions about the implementation, challenges, and outcomes of my projects, testing both my technical and practical knowledge. 2. HR Interview (30 minutes): This round happened a week later and included behavioral questions such as my strengths and weaknesses, how I handle team conflicts, and examples of working under pressure.
