I applied through an employee referral. The process took 2 weeks. I interviewed at Zscaler (San Jose, CA) in Jun 2021
Interview
3 rounds of technical + hiring manager. Tailored to the level - not just algorithmic problems. Non-programatic problems come from the real job challenges which makes them interesting and relevant. Interviewers are respectful, punctual and engaged.

I applied in-person. The process took 1 day. I interviewed at Zscaler (Bengaluru) in Aug 2024
Interview
HR kept rescheduling the interview for 2 weeks. The interviewer was a director of engineering and was very professional and patiently answered my questions as well. Got rejected before technical round though.

Question 1
General leadership related questions you've heard before already.
I applied online. The process took 2 weeks. I interviewed at Zscaler in Jun 2024
Interview
1. Call with the recruiter --> just data gathering
2. Call with hiring manager --> Conversation about my experience, current projects, etc. He was a zscaler veteran, but was very understanding and eager to listen to my projects and explain their product and its future.
3. Then came the panel interview on 3 different days. The interview panel was a group of people with 10+ years experience in zscaler. I have given interviews in similar places, but here I felt an arrogant tone and entitlement
Interview questions [3]
Question 1
Questions about a recent big project, some sample Java coding, very superficial.
Again some more details about projects, more of a deep dive into projects. The interviewer was from India, so I had to schedule a late-night interview. The interviewer was with the company for about 12 years, so he was showing some attitude initially, once I explained about the complexity of my projects and showcased my level of understanding about the problems I was working with, he was eased a bit and talked to me nice. The interviewer also asked me to code in Java just to understand my level of comfort in Java,
The question was to write a decision-maker routine that would determine if the service has to route the request to cache or to the db.
The 3rd-panel interview was the worst. The interviewer was with zscaler for 15 years. He was traveling to India, so I had to schedule an early morning interview. His attitude was worse. HE was talking to me like, everything I wrote in my resume was fake. The conversation did not begin with a tone where he genuinely wanted to know what I know, instead he was trying to have his gotcha moment! Grow up ppl.
A deep dive into projects again and a java question.
Get top N transactions of a particular type. Write methods to ingest transactions and get transactions. The returned transaction would have details if the txn is elible for rewards. good question,
