I applied online. The process took 2 months. I interviewed at Zscaler
Interview
Interview had 3 rounds - 2 technical and 1 HR. Technical interview is highly focused around networking. If you have some working knowledge of python especially testing frameworks like pytest(most my questions were around it), it will help. Technically you'll be grinded to test the depth of your knowledge in networking so prepare well. One round was with a single person and one round had 3 panelists each taking turns to ask questions around networking. In coding they asked some theoretical questions first then asked me to solve a coding problem.

I applied through university. The process took 4 weeks. I interviewed at Zscaler (Mohali, Punjab) in Oct 2023
Interview
In total 3 interview rounds were carried out. First 2 were majorly technical and round 3 was technical along with HR. The technical questions revolved around concepts of Computer Network and Operating System. Questions from different programming languages were also asked. The coding questions which i was asked were on the easy side.
The process took 4 weeks. I interviewed at Zscaler (New Delhi)
Interview
The first interview went well but the second was an absolute disaster. Firstly I took a leave from work to give that interview and then the interviewer didn't remember about the interview. The next day I told them to schedule it a bit later as I couldn't take another leave so they did. Just a little suggestion to the HR and the companies. An interview might be a everyday thing for you or just a mundane task but for a candidate it's a life changing opportunity. Please, if you don't have the time, don't take anyone's interviewer. The lady I interviewed with was taking my interview on her phone while she was handling her kid who, btw, was crying all the way. I understand that as a mother she has responsibilities but you can't put a candidate's once in a lifetime opportunity at risk just because you have more responsibilities. I am someone's kid as well. You have every right to take care of you kids and give them time but just for some extra money you take these interviews for granted. This is extremely unprofessional behavior. Never expected this from Zscaler. Be more considerate because even your kids will face an interview someday.
