Pros
Zscaler is an organization where every employee has an important role to play in company's march towards success. Here you'll find people who have passion to learn and to work. I have been with Zscaler for over 4 years and seen this company build real cloud security technology and become the market leader. Which other company can claim protecting over 10 million users from 180 countries? If you are looking for some place where you can learn and get freedom to innovate, where you won't have to worry about petty politics, where you can implement your ideas and make them valuable for the company, Zscaler is the right place for you
Cons
Not a good place to get ahead by playing politics and not delivering results. So, not everybody will be happy here :)
