    Systems Engineering Interview

    Anonymous Employee in New York, NY
    Accepted Offer
    Positive Experience
    Average Interview

    Application

    I applied through college or university. The process took 3+ months. I interviewed at Silicon Labs (New York, NY).

    Interview

    Met Silicon Labs representatives at a career fair at my university. Had a technical chat with an applications engineer and after talking for about 10-15 minutes, he said that I should expect a call within a couple of months. The representative was very professional and friendly. Roughly 3 months later, I got an email from them asking me to schedule for a telephonic interview. A couple of weeks later I had an hour long interview with an engineering hiring manager. He started with behavioral questions and then continued to ask questions about projects on my resume. Then, he tested me a bit on RF basics. The questions were fairly straightforward. Overall, the interviewer was very professional and seemed to be more interested in the methodology of how I got the answers than the answers themselves (which I consider a sign of a good company culture).

    Interview Questions

    • In-depth questions about projects related to the job description (E.g: Since my projects were mainly in antenna design, I was asked, how do I start designing antennas and which starting parameters do I take into account before starting my design)   1 Answer

    Application

    I applied through a recruiter. I interviewed at Silicon Labs in June 2017.

    Interview

    I was contacted by the company recruiter from Austin via LinkedIn, and I phone screened with a senior director of QA in Boston the very next day. I was scheduled for an in person interview in Austin 3 days later.

    This was a 2 hour interview with 3 people. This was the most unorganized interview I have ever been invited to. The last interviewer in particular, a new SQA Manager, didn't even come prepared with my resume, he said he had my resume on his cell phone, yet he didn't look at his cell phone once.

    This young manager had no sense for how to interview. He would make a general statement, then leave it up to me to extrapolate from that an actual interview question, then attempt to answer that question. Very odd. This guy was such a poor interviewer, the only questions that he could ask were to ask me for specific details with how I was performing QA on my current employers products. I explained to him that this is a breach of my current employer's NDA - disclosing company secrets - but he cut me off mid sentence while saying that, to ask yet another pointless question.

    Even though this was not going to be my reporting manager, if I was offered the job, it bothered me that someone that had zero interview skills would ever be promoted to a management position. Without waiting for any type of interview feedback, I emailed the recruiter afterwards to inform him that I would never consider an offer, should one be extended.

    Easy Interview

    Application

    I applied through college or university. I interviewed at Silicon Labs (Austin, TX) in March 2017.

    Interview

    The company contacts school to recruit student. Signed up for interview at school (ACC) and it took 30 min each candidate. The question is not hard and easy. Total 14 people signed up for interview, only 8 get onsite interview. Interestingly those 6 who are not chosen are all Asia(5)n and 1 guy with years of experience. This company has a reputation of discriminated against minority and only pick young people. If you are minority, you won't have chance. People who work there also agree with the way they hire people but not dare to say. They should be investigated about hiring policy and practice.
