    ASIC DesignPosition Interview

    Negative Experience
    Average Interview

    Application

    I applied through college or university. The process took a week. I interviewed at Ambarella (Los Angeles, CA) in February 2017.

    Interview

    I got contacted by Ambarella HR one week after I submitted my resume at school career fair. I was scheduled to talk with a senior engineer from the ASIC design team. He started with general questions about my resume, went into details of several projects I listed. Then he began to ask technical questions about Verilog basics, bits operation, digital circuits and etc. The question is very basic but covers a lot. The guys who talked to me was very nice and patient that he would guide me through the thinking process when I got stuck at his questions. Although I managed to answered most of his questions, I did't feel I did good enough to get the job.

    After my first phone screen, I had not heard from them EVER again. I did not receive any email regarding my application progress nor did I get any rejection letter. Neither did the HR replied to any of my email ever since. Such irrespective attitude toward their applicant reflects their company culture from my personal opinion.

    Positive Experience
    Easy Interview

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at Ambarella (Santa Clara, CA) in September 2014.

    Interview

    Connected via a recruiter who had placed another candidate in the same group. Drove to Santa Clara campus on 3 different days to interview with a total of 5 people (the entire group), plus an internal HR person.
    I found the people very friendly and had a good vibe about the company. I breezed through the interviews and found them to be not terribly technically challenging. However, I am a long-time computer architect with detailed hardware modeling experience, and I believe they want a more software-centric person.

    Interview Questions

    • Question dealing with I/O in C++. This does not come up very often in hardware modeling.   1 Answer
