Pros
People: Get to work with friendly people who are tight-knit and helpful. Career Progress: It's a great launchpad for career growth and to learn data analysis useful for management careers later. Promotions are fair -- based on performance/merit,
Cons
Brand Value: What was initially seen as a top employer in IITs/NITs are now seen as a Tier-3 recruited in the league of Infy, Cognizant. ZS competes with Infy-type companies on a regular basis, and its glorified brand of 'consulting' is falling apart. Culture: Leadership is less approachable with the increasing headcount, and certainly the quality of people joining the firm is not as good as it used to be. One of the senior leaders in his words - "We don't need super smart 8+ pointers from IITs/NITs to do the work we do". I completely agree with this person, the quality of work we do has also diminished. Compensation and Bonus: A black box. There is no clarity in how one's salary increments are made, and bonuses paid.
