Junior Software Development Engineer Interview

Junior Software Development Engineer
Sunnyvale, CA

I applied online and the process took 2 weeks - interviewed at Fortinet in April 2014.

Interview Details – I initially had a short chat on the phone with the recruiter and she explained what the company does and what the role is etc. She then set up a technical onsite interview with 2 engineers for 1 hour. The engineers had a hard time communicating in English and kept talking to each other during the interview in Chinese which was very unprofessional. Although I applied to a front end role, they asked me questions on C/C++. I was asked to write on the board- most of the questions were on array manipulations and circular array implementations.

After a week, I was contacted for another onsite interview with the hiring manager and VP. The hiring manager asked me questions on hashing and networking. Later the VP asked behavioral questions, my salary expectations and indicated that everyone likes me and that he is planning to hire me.

Interview Questions

Negotiation Details – I was asked what my salary expectation was and I told them to which they agreed. They also have good RSU stock options to choose.

Human Resources Position Interview

Human Resources Position
Sunnyvale, CA

I applied through a recruiter and the process took 2+ weeks - interviewed at Fortinet.

Interview Details – Contact was initiated by HR via professional network site. Went through phone interview with a recruiter and then on-site interview with 3 people over a 2 hour period and then final phone interview with an off-site senior manager. I was informed I would receive a response via a specific timeframe. It was the last I heard from anyone.

Overall interview process was positive, but it was rather unprofessional that I was told that I would be contacted again within a certain timeframe and there was no communication follow through.
