    Product Engineer Interview

    Anonymous Interview Candidate in Neenah, WI
    Anonymous Interview Candidate in Neenah, WI
    Application Details

    I applied in-person. The process took 2 daysinterviewed at Plexus in April 2011.

    Interview Details

    Phone interview was brief and to the point. Prior experience, company values - overall just a screening.

    Tour of the company followed at my next visit. The premises are impressive on the manufacturing floor.

    In person interview was quite difficult. Round-Robin style group interview took place after I took 15 minutes to present myself and my prior experiences. The group interview was difficult mainly because each interviewer had a specific set of questions to ask, and each question could compound off the previous answer you gave. Be careful with what examples that you use from your previous experience.

    Technical questions were present but minimal for an engineering position. Total time elapsed for the interview was 1 hour 30 minutes.

    Application Details

    I applied online – interviewed at Plexus in July 2014.

    Interview Details

    Interestingly, had to prepare and deliver a PowerPoint presentation on why I should be hired. Wasn't given the presentation template until the night before and had to email it by 9:00am the next day. HR Recruiter thought it was a great presentation although the audience provided very little feedback. Audience was another HR person, 3 program managers and the operations manager.

    Design Engineer Graduate Trainee Interview

    Anonymous Interview Candidate in Bayan Lepas (Malaysia)
    Anonymous Interview Candidate in Bayan Lepas (Malaysia)
    Application Details

    I applied online. The process took 4 weeksinterviewed at Plexus.

    Interview Details

    Process was quick and efficient. Possibly because I had a previous interview for another position with a hiring manager related to the department, so the initial interview used material and feedback from the previous interview.

    For the sake of convenience and efficiency I'll merge the reviews of both interviews into one since it was for a very similar position.

    First interview was very technical since it was an interview for a junior executive position. Continuously throughout the interview the hiring manager was probing my knowledge in the technical area to ascertain if I had knowledge in areas either dealing directly with the job or related to the job scope. There was a lot of interaction and enthusiasm which is a very inspiring aspect which I observed to be severely lacking in most interviews with other employers. There was some discussion and some teaching/learning of new things on a whiteboard - which was used as material for questions which followed. A week after the interview I was informed that unfortunately a more experienced candidate got the job, but they soon referred me to a very similar position(only with the title of graduate trainee and the option to learn from an array of other departments before being converted to permanent). This leads me to the second interview.

    Second interview was not so technical, but more of a behaviourial analysis and aptitude analysis, determining which departments or areas I was more inclined towards, in addition to gauging my passion. The director of operations introduced me to the different functional managers and had us exchange knowledge, further affirming and categorizing areas in which I am interested in, or could improve on. After meeting the other managers, it further augmented my interest in the company as the motivation, enthusiasm, and knowledge I observed in the manager during the previous interview did not appear to be a one-off occurence.

    Interview Questions
    • Some questions that were asked(may not be exact question, but rather as I understood or remember them):

      Q: Explain or share knowledge of RTOS(Real-Time Operating System)
      A: I didn't know what they were, but was offered a brief explanation.

      Q: Now that you know what RTOS is, given a printer, would you rather use a RTOS or a regular operating system such as, windows or linux in it.
      A: No correct answer, but rather the interviewer wished to see my train of thought.

      Q: Have you heard of an Interrupt before?
      A: I didn't know but they shared with me what it was. Google it up, Interrupt handler.

      Q: Given a function:
      int func(int *x)
      {
      int t;
      t = *x * *x;
      return t;
      }
      A: I think ths is simple enough, it's a function which squares the value at the given memory location.

      Q: And here's the relatively tough one. You are given a microprocessor and a square clock wave entering it. The clock wave has a maximum frequency of 250hz. Within a tolerance of 25%-75%, design a function within the microprocessor which interates at a certain interval, x, which will calculate the average frequency of the input clock wave.

      A: At first I didn't get the answer but after some illustration, the picture became clearer. What you want to do is store the previous state recorded, and then check it with current state(whether it be 0 or 1) then execute a +1 to a counter if previous state = 0 and current state = 1. Answer I gave was something like this:

      void loop()
      {
      static int prev, counter, freq, x;
      int curr;

      if(prev==0 && curr = 1)
      {
      counter++;
      }
      x++;

      freq = counter/(x)(t);
      }

      x counts the number of times the function iterates regardless of whether it has detected a change in state. t on the other hand is the timing of the loop function, found by converting the 250hz into seconds(4ms) and then taking the value of 25% - 75% of that 4ms.

    Analog Engineer Interview

    Anonymous Interview Candidate in Raleigh, NC
    Anonymous Interview Candidate in Raleigh, NC
    Application Details

    I applied through college or university. The process took 2 daysinterviewed at Plexus in October 2010.

    Interview Details

    The first interviewer was a new engineer coming to recruit for Plexus. The on-site interview first started with a benefits briefing followed by technical questions. The technical questions were presented by two engineers. The subject was about circuit analysis and practical components. After this I spoke two different managers. One was a project manager and the other was a staffing manager. I spoke to the project manager first and he asked about my college experience and projects that I have worked on. He also asked what I would do to design a headphone amplifier. The staffing manager would be given projects and then assign manpower to those specific projects. The project manager would be in charge of said projects. If you had a problem, then you could go and see the staffing manager. The staffing manager asked me where I felt that I could fit in. I faltered and said that I could see myself in any position. I should have stated a more assertive answer. Finally there was a group interview at lunch, which was a behavioral interview. I should have expressed myself more freely and more confidently. I learned a lot from this process and will become better at this process.

    Senior Embedded Software Engineer Interview

    Anonymous Interview Candidate
    Application Details

    I applied online. The process took a weekinterviewed at Plexus.

    Interview Details

    Applied from India through linkedin for a Malaysia based position. Initially they ask you to fill up a skill set form wherein you list the competencies for the mentioned platforms/tools/programming languages etc. Based on the information they decide to proceed. Got a confirmation for technical skype call with functional manager in Malaysia. The call lasted for 1.5 hrs with majority of the questions based on embedded C. Not very difficult. Finally one design question on describing various modules of vending machine from embedded developer point of view. The call went fine. Finally manager asked about the salary expectation. I had done a little research on the salary part prior to the interview and based on the information available it seemed Malaysia did not offer much significant advantage in terms of compensation. I mentioned 5 times the monthly living cost which was probably too much to ask for.

    HR did not bother to give any feedback proactively as well as not even after asking for it.

    I applied through college or university. The process took 4 weeksinterviewed at Plexus.

    Interview Details

    Talked to a recruiter at a career fair, then the next day (or 2 days later) had an interview on campus. Pretty routine interview asking me about my resume and experiences. He said he'd recommend me for the next step, and a week or two later I got an email from them. I drove out to Neenah WI (they paid for gas and the hotel), and had an all day interview consisting of a tour, meeting with HR (they went over benefits, which I thought was really weird), and a couple of skills tests. One test was about the software process (requirements, design, implementation, etc), and one was a programming test. They said they had the same test for all skill levels, and I missed a fair amount of questions. Got an offer a week later via email.

    Interview Details

    was young and looking to move West to enjoy the Rocky Mountains.
    The hiring engagement was pretty straight forward. The initial HR representative that I spoke to seemed a bit unpolished, but once you get through to a hiring manger it is much better. For electrical engineering positions you should expect a standard battery of technical questions starting from basic to more advanced – dust off you college text books. People were friendly and seemed to like their jobs. It took a long time for them to tell me one way or another if I got the job. I did not appreciate that.
