I applied through a recruiter. I interviewed at Fortinet (Sunnyvale, CA) in Sept 2025
Interview
There is hacker rank test and also you are assigned to a recruiter which are very caring and patient people. After that there will be two rounds of interview questions mostly technical. they wanted to know why I am leaving my job.
Interview questions [1]
Question 1
Mostly L to L networking questions, ensure you study basic networking and some cyber security. One thing I wish it was different, the interviewer all did not turn on camera, and I was talking to a two images with big letter of their initial on it. that was scary part since I could not see any face impression and both were ESL, but patient.
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.
