Process Development Engineer Interview

Difficult Interview

Application

I applied online. I interviewed at Cree in May 2017.

Interview

The process consists of a questionnaire, phone interview, Skype presentation of research or some relevant project, and finally an on-site interview. I was only considered up to the presentation stage, where I was asked questions about my undergraduate research that were beyond the undergraduate level of technical expertise. It was at this point that I was disqualified. The questions asked were directed at a specific answer, and if that answer was not given, the interviewer continued to ask the same question in different ways to "direct" the interviewee to the answer. If the correct answer is not given, the process ends up making the interviewee look completely incompetent, even though the questioning method is not optimal.

Interview Questions

  • You are given 2 sand timers, one with 4 minutes of sand, and one with 7 minutes of sand, and you are asked to use these to measure exactly 9 continuous minutes of time to boil an egg. without estimating time remaining visually, how can you precisely time this cooking process?   1 Answer
  • Given 9 billiard balls, with one out of 9 exhibiting a significantly different weight from the rest, and using a balance to measure mass, what is the minimum number of measurements that must be taken to be certain of which ball is the heavy one?   1 Answer

    Difficult Interview

    Application

    I applied online. I interviewed at Cree (Durham, NC) in April 2017.

    Interview

    Originally, I applied for a different engineering position. I was asked to fill out a thorough questionnaire that was sometimes referred to in later phone, Skype, and in-person interviews. I then had a phone interview. Following that I gave a Skype presentation (30 minutes) on a previous project. 1-2 months later I finally received clear information that the position was given to someone else, but HR submitted my profile for a brand new position. During those 1-2 months, I was being told that audits were being conducted so the managers couldn't give me further information. I then gave another Skype presentation for the new position and was brought in for an on-site interview about 2 weeks later. At the start of the interview I found out Cree had plainly lied to me about the 1-2 month delay, because it turns out they just wanted to offer the previous position to another applicant who had already interviewed by the time they were considering bringing me in for an on-site interview.

    The on-site interview was a long day, and a generally neutral experience. As expected, they were extremely technical and asked many questions to see how you thought "on your feet." One manager criticized me for not having an engineering position already since graduating university, as if I could control that, and was accusatory in many of his questions. He had obviously had formed his own negative impression of me before he met me, though he was the exception. OVERALL, Cree offered poor and dishonest communication and one interviewer was belligerent, but most interviewers were simply curious and technical. I'm not terribly disappointed I was not given an offer in light of my application and interview experience.

    Interview Questions

    • The brain teasers were fairly straightforward. I can only remember a few.
      1) Estimate the circumference of the earth
      2) How tall would you be if your atoms were the size of tennis balls?
      3) How old are my children if their ages add up to 'x' and the difference between them is 'y'
      4) If I had two sand-timers of 4 minutes and 7 minutes, how could I accurately measure 9 minutes?
