I applied online. The process took 2 weeks. I interviewed at Zscaler (New Delhi)
Interview
Illogical questions were asked. They don't ask questions related to what you know. They seem uninterested. They rescheduled the interview a 100 times. They expect you to by-heart commands(linux or windows). No respect to what you know or your knowledge. They pretend to treat you like inferiors if you are unable to answer questions of their "domain".
Interview questions [1]
Question 1
linux commabd for this , windows command for that ... he wanted me to know everything by-heart.
