Zscaler Software Engineer interview experience

The focus was on data structures and algorithms, computer networks, and operating systems, with a strong expectation that I could code and reason through problems. I also remember that understanding Zscaler’s products in network security and cloud services was part of what they seemed to want.

The whole thing felt difficult on the technical axis, and the questions demanded real depth rather than memorization. I ultimately didn’t get an offer, but the process pushed me hard enough that it stayed memorable.
