I applied online. The process took 4 months. I interviewed at Fortinet (Sunnyvale, CA) in May 2022
Interview
Awful. Made me feel like trash every time I even paused. Constantly assumed I couldn’t do anything right. One of them had the nerve to raise their voice at me when I didn’t understand something. Overall, not great.
10 MC, 4 coding. Haven't reached the next stage yet. But coding was in C and was okay just leetcode easy for first 2 and leetcode medium for the last 2.
I applied through an employee referral. I interviewed at Fortinet (Vancouver, BC) in Feb 2026
Interview
Horrible experience, especially with recruiting but also the attitude of the hiring team. Recruiters love to cold call with no heads up (only out of hundreds of companies who use standard emails) and are very disorganized, forgetting details about me and saying nothing about the team or company.
Process:
- 2.5 hour OA with complete silence for 1.5 months after
- 2 hour in person onsite interview. The interviewers had a cold attitude and look throughout. Didn't bother to introduce themselves or the team. Didn't even say goodbye or thank me for my time after the interview despite me taking PTO.
- 3 weeks later, recruiter called to setup a call with another manager. This manager asked random questions and didn't explain his role or give me any time to ask questions. Overall easy conversation.
Complete ghosting from the company after the final call despite me following up twice. I only found out through internal sources that the position was filled.
Be aware of this company. Heavily favour onsite work and a certain demographic. Be prepared to job hop after a year even if you get a offer.
