    Negative Experience
    Average Interview


    I applied online. The process took 2 weeks. I interviewed at Infinera (Santa Clara, CA) in April 2020.


    Applied online and got a notice that I would have a set of technical screening. Spoke with three people for an hour each, then the manager for 30 minutes. Each interviewer asked his/her set of questions. Each told me how stressful the job was and that they spend long hours working there. I asked what they did for fun and none of them could say which was odd to me.

    Interview Questions

    • I was asked about the difference between mutex and semaphore. I was asked about how to avoid deadlocks. Those were fair questions. Then I was asked about difficult bugs and how I got through it. Also fair. Be prepared to deal with computer architecture questions as if you just got out of school. Each interviewer told me that the job takes long hours and was high stress. Even the manager told me this. The manager asked me what bugs did I cause as if I purposely caused a bug. They were going out of their way to not accept me maybe because of cultural reasons. Very strange. I didn't get the job but people should be warned.   Answer Question
