I applied through a recruiter. The process took 5 weeks. I interviewed at Zscaler in Apr 2025
Interview
The overall interview process was fairly standard. It began with an HR round that lasted around 15–20 minutes, followed by three technical rounds. I believe I performed well throughout, and I was informed afterward that the feedback from the technical rounds was positive.
However, despite the encouraging feedback, I was later told by the HR representative that the position had been elevated to a more senior role, and the team felt I would not be the right fit for this updated requirement.
While I appreciate the opportunity to interview, I was disappointed with the outcome—especially after receiving positive feedback and investing significant time and effort. Clearer communication regarding potential changes to the role earlier in the process would have been helpful and more respectful of candidates’ time and expectations.
Interview questions [1]
Question 1
Networking, previous projects and tech stacks used along with some DSA questions
I applied through a recruiter. The process took 4 days. I interviewed at Zscaler in Jan 2024
Interview
Received a rejection mail for my domain expertise role. Recruiter reached out on the same day for two other roles.
Round 1: Technical round. Questions around past project architecture, challenges and an LC question.
Round 2: Asked an DSA problem but had to code in Java only.
I struggled with the code as I transitioned to Python, C# and have been interviewing in C++ for DSA. Unfortunately, there is no flexibility for choice of language because the team's tech stack is Java and the interview is focused more on tech stack knowledge.
The interviewers were professional and polite. The second interviewer asked to contact recruiter once I have refreshed on Java.
