1. Call with the recruiter: Just data gathering.

2. Call with the 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. Panel interview on three different days: The interview panel was a group of people with 10+ years of experience at Zscaler. I have given interviews in similar places, but here I felt an arrogant tone and entitlement.

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 had been 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 eased up a bit and talked to me nicely. 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 had been 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, people.

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 eligible for rewards. Good question.
