Zscaler Interview Questions

Application

I applied online. The process took a week. I interviewed at Zscaler in January 2020.

Interview

Initial phone screen with recruiter and then 1 week later a call with hiring manager. Phone screen went well but the interview with hiring manager was a little difficult as his expectations were way out of synch with the recruiter. I never heard back even though the hiring manager wanted to have another phone discussion.

Interview

Long process, multiple interviews. first coding interview online, then corp HR interview, then technical interview with local office engineer. Final interview with additional local office staff. Technical interview with engineer was difficult, they ask about mostly theoretical concepts, not hands-on skills.

Application

I applied through college or university. I interviewed at Zscaler in November 2019.

Interview

They were helpful and I had the online assessment which was easy/normal I think. After that, they have the 2 other phone interviews and one on site interview. Overall, it was a positive experience.

Application

I applied through a recruiter. The process took 2 weeks. I interviewed at Zscaler (San Jose, CA (US)).

Interview

The recruiter reached out via Inmail on LinkedIn. A phone call with the hiring manager and a traditional Desi type panel interview consisting of 5 team members including the hiring manager. Two of the engineers did not show up to work and the interview ended 1 hour earlier.

Hiring Manager - A cool guy who mostly aimed at extracting information from you in all possible ways. One of the better interview experiences in recent times.

Interviewer 1 - A middle-aged guy who was obsessed with HTTP. He started with versions of HTTP and went on with headers, header format for Request, header format for Response, and whatever possible he could think of HTTP.
Disclaimer - I wasn't able to answer most of the questions, and I failed to understand the obsession with all the HTTP questions. He did not even ask a word apart from HTTP and walked out.

Interviewer 2 - This guy attended the call remotely. Started off with HTTP stuff again. He suggested TRACEROUTE works using ICMP, but my dear brother please revise your networking basics before interviewing. Traceroute uses UDP on a Linux machine and ICMP on a windows machine. Now you remember who I am. :)

Interviewer3 - A decent guy who again asked me about Postman, another HTTP related question. Asked me about IPSec, and other methods.

Overall, the interview process was more focused on how a direct competitor (the company i worked for) solved issues differently, rather than what I knew and what role i played.

There were absolutely ZERO programming questions, NO preference to Automation, I did not even write a single IF statement on the board.

I applied online. The process took 4 weeks. I interviewed at Zscaler.

Interview

The hiring process was quick but highly in-efficient; I applied online using the company portal and got a response from the recruiter the next day for a quick phone call. The call went well and he put me through to speak with the hiring manager. The schedules were changed a couple of times at the last moment and finally, I managed to speak with the hiring manager. The conversations went well and the manager mentioned about bringing me in onsite soon.

The onsite interview was scheduled for 4 hours with 4 different interviewers. This was not the panel interview that Zscaler usually does for other positions. I was called in at 9 am, and no one showed up till 9.30. This felt not good, to begin with. Met with the SVP to start the interview and was asked questions around my background; what I currently do etc.

For my 2nd interview slot; the interviewer just didn't show up! The recruiter was kind enough to stay with me during that time. Then the interviewer shows up and acts all pricey! I mean, yes you might be a VP at Zscaler, but doesn't mean you make others feel they know nothing! Then the hiring manager was scheduled but could not make it. I guess you get the point on how organized these folks are.
I got a clue and in my mind, I already knew this is not the right place to work. Again; asked a couple of friends who work here, and they mention employees are not valued.
Also; the hiring manager not showing up for the interview at least to see off; that's really a huge red flag to me.!
On a positive note; instead of keeping me hanging; I was happy that they at least responded with rejection and lo and behold! The reason was not enough experience! Did someone not even read my resume, to begin with? :)

Application

I applied through an employee referral. The process took 6 weeks. I interviewed at Zscaler (Chicago, IL (US)).

Interview

The interview process is detailed, multi-step and incredibly exciting. You speak with many people within the organization (not just those directly impacted by your role) to ensure you are not only a fit for your role, but also an asset to the company culture.

Application

I applied online. The process took 3 weeks. I interviewed at Zscaler in July 2019.

Interview

I applied online. Received an OA first. The OA has different types of questions including filling in the blanks and MCQ. I thought that I did not do very well in the OA but I still got a phone call with the recruiter.
However, I got rejected after the phone call with the recruiter and I have no idea why. Probably they evaluated the results of OA after the phone call with recruiter.
