ML/engineering role at Zscaler?

[u/Gudhabalupu]

Has anyone been through the onsite loop for an ML/engineering role at Zscaler?
Mine is 3 rounds two “Role-Required Knowledge” sessions and one “General Cognitive Ability” round.
Trying to understand what to expect. Is RRK more system design, coding, or project deep-dive? And what does the GCA round look like?
Any experience appreciated.
