The first technical round focused entirely on system design, along with one problem related to HashMap.The second technical round was centered around Spring and core Java concepts.The third round involved a few coding practice questions and one problem to solve.The Director-level round was completely behavioral. In director round asked about my expected salary.The VP-level round was a mix of technical and behavioral questions.All the rounds went well. The HR round was a bit unusual. The HR seemed partially sleepy during the conversation—she yawned in between questions, then suddenly woke up and asked for clarity on my answers. She asked about AI-related I realised she doen't have any understanding about AI. The online question was one medium and other above medium level.All completed after a week I called recruiter , The way he speaks almost confirm the offer and a week later recruiter updated they stop proceeding this process and he ask me how the HR interview went??
