    Interview

    I thought that my to-be manager was discourteous and disingenuous in our interview, and hoped that they weren't so in normal situation. I felt like they wanted to pry into my past and future decisions until they saw a good reason not to advance me. I was surprised because their actions did not match what I knew about Cirrus Logic from company website and secondary testimonies.

    Design Verification Engineer Interview

    Negative Experience
    Average Interview

    Application

    I applied through a staffing agency. The process took 3+ weeks. I interviewed at Cirrus Logic (Austin, TX) in July 2017.

    Interview

    This is not a place that experienced/senior engineers should look to. They seem to have more work than people to do it and are looking to scale through hiring more bodies than changing how they actually do verification reuse. They rely mostly on external recruiters not only for finding candidates but also as agents throughout the whole process so you're mostly dealing with a distant third party headhunter who knows little about the role, industry, or expectations.

    The pre-interview process involved a prescreen call and testbench coding exercise that a candidate does on their own time followed by a technical review call. The onsite interview was not effectively geared towards a Senior person and also involved an on-demand coding activity which was vague and wouldn't reveal much about DV expertise.
    Despite initial positive feedback and follow-up calls, the company took over 2 weeks to respond (via their 3rd party head hunter) with disappointing news and absolutely no other feedback.

    Interview

    Two phone screenings and then onsite interview with the whole team. They were very courteous and welcoming. You have to go into each individual's office and answer questions. They ask you to draw on the board. They asked mostly technical questions and a few personal questions such as career goals and motivation.

    Difficult Interview

    Application

    I applied online. The process took 4+ weeks. I interviewed at Cirrus Logic (Austin, TX) in March 2017.

    Interview

    Applied online at their Career portal and got a call few days later to set up a time for phone screenings. 2 phone screenings before I was invited for onsite interviews. 8 onsite interviews followed back to back, each 1 hour long. The first interviewer was not professional at all and kept asking things even when he admitted that he was out of touch with those concepts for a really long time. The hiring manager took for lunch and interviewed at the same time.
    Questions listed below

    • Phone Screening:
      - Digital design fundamentals, CDC, Verification fundamentals, questions related to coursework, Analog fundamentals, and finally some take home problems that I answered within 24 hours.

    Easy Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Cirrus Logic (Austin, TX) in December 2016.

    Interview

    This was the most unprofessional interview experience ever. No questions were asked based on my skill set in my resume. They gave me a problem to solve (design and verify) which I was fine with, but in the meanwhile the interviewers were discussing some random stuff not related to the interview which was distracting. They were least bit interested in what i did and it was extremely unprofessional. The worst is they never got back me to with the interview result.
