valid brackets on leetcode and we dove a bit deeper
First there was an online assesment and two rounds of tech interview where each round had 2 dsa problems which were lc medium and some behavioral questions and project related question.
The interview process was straightforward and friendly. It started with a recruiter screening, followed by a technical interview. The interviewer asked basic coding questions, object-oriented programming concepts, and a few behavioral questions based on Amazon Leadership Principles. The coding problems were not very difficult, and the interviewer was willing to provide hints when needed. Overall, the experience was positive and well organized.
