    Applications Engineer Interview

    Anonymous Interview Candidate in Austin, TX
    No Offer
    Positive Experience
    Easy Interview


    I applied online. The process took 5 weeks. I interviewed at Microsemi (Austin, TX).


    I applied online, it took about 4 weeks before I first got contacted by HR for screening. Questions were very generic and straightforward. Few days later, I received an email for a phone interview with the hiring manager. The interview went well and questions were not specific to the technicality of the role per say, but more about soft skills and problem solving, i.e. interacting with internal and external stake holders It was a good interview and the hiring manager sounded very reasonable. I simply didn't pursue it further as I learned that it was intended more for junior / new grad
