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

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.

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.
