CleverTap Software Developer interview questions

The first round began with a self-introduction, followed by basic questions from OOP, Computer Networks, and DBMS. They asked about the four pillars of OOP, ACID properties, virtual memory, and similar foundational topics. After that, I was given a DSA problem where I had an integer array nums and had to find the subarray with the maximum product and return that product. Next, they asked about my projects and some detailed questions related to them. With this, the first round concluded, and I was selected for the second round. The second round again started with a self-introduction, followed by more questions on OOP and DBMS, as well as an in-depth discussion about my project. For the DSA problem in this round, I was asked to solve a binary tree traversal question. However, I was not selected for the third round.
