Zscaler Software Engineer(Internship) interview questions

Here’s how the process went: 🧠 Online Assessment (9 Nov 2025) The test had two sections: • A DSA/backend section where we could use our preferred language (I chose C++) • A mandatory Python section The questions were medium to hard level and focused on problem-solving and core DSA concepts. I was happy to clear this round. 🏢 Pre-Interview Sessions (18–19 Nov) We had sessions about Zscaler’s journey and the interview process. This gave a good idea about the company and what they look for in candidates. 💻 Technical Interview (28 Nov 2025) This round was with Narciso Luque and lasted around 75 minutes. It mainly focused on DSA and problem-solving at a medium level. The interviewer was very friendly and made the discussion comfortable, which helped me think more clearly. I really enjoyed this round and was glad to move forward. 🗣️ HR / Managerial Round (1 Dec 2025) This round was with Constantin Miroslav and focused on behavioral questions. Most of the discussion was about how I handled real-life challenges and situations in the past. I was a bit nervous, but the interviewer helped me feel at ease.

There were 4 question in total and I didn't pass the OA, 2 DSA questions in Java/C++ and 2 in python. The total time was 2 hours for the questions
