Zscaler Principal Software Engineer interview questions

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,
