Pros

Cutting-edge technology stack — Working on zero-trust network architecture, high-performance C++ datapath, and distributed systems gives you excellent technical depth. Great for résumé building. Technically challenging problems — Real-world scale issues (P0/P1 incidents, multi-tenant proxies, TLS/DTLS at wire speed) keep you sharp. Decent compensation — Base pay is competitive for India standards, especially at senior levels.

Cons

Severe India vs. US disparity — Good, visible work is consistently credited to US counterparts. When something goes wrong, blame flows downstream to India. This double standard is demoralizing and never addressed by leadership. Rampant office politics — Career growth is driven more by who you know than what you deliver. Meritocracy is a stated value, not a practiced one. Micromanagement culture — Despite hiring experienced engineers, managers frequently second-guess decisions, require unnecessary check-ins, and undermine engineer autonomy. Managers lack people skills — Several engineering managers in the ZPA org are technically okay but fundamentally lack empathy, communication, and the ability to build psychologically safe teams. Zero team culture in ZPA Broker org — Engineers operate in silos. Asking for help is often met with indifference or passive gatekeeping. Knowledge hoarding is a survival strategy here, not an anomaly. Toxic individualism — Highly competitive in the worst way — not healthy competition that raises the team, but cutthroat behavior where colleagues actively avoid helping peers to protect their own visibility. Favouritism is real and visible — Certain employees get preferential treatment in promotions, project assignments, and performance reviews regardless of contribution. No psychological safety — Raising concerns, flagging inefficiencies, or giving honest feedback is career-limiting. The culture rewards silence.

Pros

Zscaler’s bread and butter products are great. Excellent pay and benefits. Fast growing technology

Cons

Toxic Mid Level Management looking out for themselves. Employees are easily expendable. Company seems fixated on stock prices and losing its focus on making happy customers. Diabolical review practices. My whole team received reviews from our manager. The SVP of the group then lowered everyone’s rating down a full level without any feedback or reason. The same SVP then laid us all off a few months later.
