OA Difficulty and Content
At Zscaler, I found that the OA tends to be a bit tougher compared to others. I had to brace myself for lots of questions on Data Structures and Algorithms (DSA), and they weren’t easy. They really tested my coding skills. My group had to tackle four DSA questions, and none of them were about graph theory or dynamic programming. But still, I had to be ready for some serious problem-solving.
