Highly efficient interview process, respectful and communicative. Multiple interviews with stake holders ,and a final panel review which is a standard process in the software industry. That said, there where no huge time gaps between the interviews. Once one interview is done they move on to the next fast. They did not have to reschedule any calls either.
The technical part of the interview process was in depth. I recommend that you come prepared and to learn as much as possible about what the Zscaler does in the market and watch some examples on their product pitch.
There was a lot of focus on soft skills so come relaxed and answer questions with candor.
The offer letter was very detailed so you know what you're getting.
The onboarding process is stellar. They get you going quickly and you are immediately setup with the tools you need to get started.
