NCube Software Engineer Java Developer interview questions

The process has 3 stages. Began with the HR process, it took around 30 minutes with the usual questions, tell me about you and that kind of questions. The second stage was about a simple tech interview, about to solve a simple algorithm, and then to turn the answer using java 8 (stream, flatmap and collect) . The final stage where I reached was about more conceptual question, spring, aws, databases, that kind of questions.
