I applied online. The process took 5 weeks. I interviewed at Fortinet (Vancouver, BC) in Mar 2020
Interview
Basically 2 steps: online test and then in person interview. I thought i aced the interview. Almost answered everything But oh well it is what it. The only i mistake that I think i made in the hindsight is that probably i went into some unnecessary details in some of the questions. So try to stick to the point. Good luck to everyone

I applied online. The process took 3 months. I interviewed at Fortinet in Nov 2025
Interview
I spent more than 20+ hours on 5+ interviews, including a 5 hour take home test and going to their office for 3 consecutive interviews. Then I waited 1.5 months for a rejection without explanation. No respect for our time.
Interview questions [1]
Question 1
Specific questions about processes that should be written down.
Great interview experience! The focus was on networking fundamentals like LAN, OSPF, TCP/IP, and the OSI model. The questions were technical but fair, testing both theoretical knowledge and practical application. A great way to assess networking expertise.
I applied online. The process took 3 weeks. I interviewed at Fortinet (Ottawa, ON) in Dec 2024
Interview
I had interview for the “Technical support Engineer” at Fortinet on Dec 6th 2024.
After first questions, "what is the 7 OSI layers and the sample protocol for each layer", the interviewer told me show him my keyboard, because he felt, I am looking too much bottom of the screen.
then he asked me to share my screen. and he said that I am using chatgpt for cheating. That chatgpt question was VRF leaking related to my task for my current job.
I have more that 15 years experience as a network engineer and consultant. I spent time to pass NSE4 certificate for this role requirement and planned to relocate to Ottawa. the interviewer stop interview easily. The interviewer didn't even turn his webcam.
