    Interview

    Another one of those companies that you interview for four hours, then get homework and then they don't have decency to get back to you because they must be so busy.

    The economy is turning around, people are going to start job jumping again. You best figure out how to treat prospective employees better.

    I think the earlier reviews were correct, this company has gone downhill.

    Interview

    Introduced Cognex, asked about my research experiences, followed with an coding question. I think they already filled that position. The interviewer was absent-minded, didn't pay attention and gave very slow response. Just waste of time. I doubt how people feel working there if the interview manager even don't show respect in the interview process.

    Application

    I applied through college or university. The process took 2 weeks. I interviewed at Cognex (Natick, MA) in October 2014.

    Interview

    It was an onsite interview. I booked my own tickets there and lived a night in Natick before my interview day. I didn't do well in the interview. And the HR asked me to mail him my receipts of transportation and hotel for reimbursement when I left. But after my interview, I sent him receipts and a follow-up email, and called him twice. But he never called me back or respond me. The front desk is also not very friendly. So overall it's a bad interview experience.

    Interview

    1) Email exchange & subsequent phone interview with HR. Asked about background, etc.
    2) Technical phone call, asked about background in comp vision, programming etc. This included the 1 programming question I was asked (*a++ = *b++). I fumbled in this answer, but I should've known this.

    They were considering me, and a possible programming test was to be scheduled. However, a few days later I emailed for an update, and the HR sent me a "dear john" email.
    I think this question is asked very often in their interviews so I should've known it, but also that they were a bit quick to judge on one question alone. I was expecting a broader range of questions.

    Difficult Interview

    Application

    I applied through college or university. The process took 3 days. I interviewed at Cognex (Natick, MA) in January 2015.

    Interview

    Full day of interviews: 5 45 minutes sessions with their different product departments, touching on many topics: C, image processing, camera models, product management, etc. Also asked me to give a 45 minute talk on a research project related to computer vision. Friendly but tough. The interviews implied that many engineers stayed on for on average at least 3 years and 10-15+ was not uncommon.

    Easy Interview

    Application

    I applied online. The process took a week. I interviewed at Cognex (Milwaukee, WI) in September 2016.

    Interview

    They called me and ask me some personal and professional questions. The interviewer was worried if I had the experience required. He didn't like it that I had only two years of c++ experience. I did not get any difficult question, most of those are when you go on site. Also they promised me to call me back later, he hanged up because he was delayed with other interviews. I wouldn't recommend
