    Difficult Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Apple in October 2016.

    Interview

    This was for the Soft Goods team. Had a quick chat with a recruiter then had a phone interview with an engineer. Got asked some weird questions about quality control even though that's not my area. Interview went well seeing how they gave me a design challenge for the next interview phase.

    Overall, Apple is very secretive and it seems like they keep you at arms length away from them. During the whole process it was difficult to gauge how I was doing during the entire process and they didn't provide very much feedback.

    Difficult Interview

    Application

    I applied through a recruiter. The process took 4+ weeks. I interviewed at Apple (Sunnyvale, CA).

    Interview

    Round 1: Phone interview with recruiter. Recruiter asked some general questions about my background and details to set up round 2.
    Round 2. Interview with Technical Manager. Was asked additional questions about my background and answered my questions about Apple
    Round 3: Design Challenge: A design prompt was given with a specific problem but very general requirements (presumably to gauge your approach and creativity). I created CAD models, FEA, and engineering analyses in a presentation that I sent them
    Round 4: On site: I was interviewed by the Senior Recruiter, three PDEs, a manager, a director, two senior designers, and the technical manager from round 2. During lunch, I had to present my design challenge which was dissected in detail. Interview questions ranged from my background to previous projects to engineering questions to test general engineering knowledge.

    All in all, it was a very thorough.

    Application

    I applied through a recruiter. The process took a week. I interviewed at Apple.

    Interview

    Contacted recruiter directly on LinkedIn, followed by a technical phone interview. The interview manager seemed to be in a hurry, called 10 minutes late and kept saying that he has just 10 minutes to finish the interview. Not much time was given to answer the questions. So in just 10 minutes - he told me about the team and work, asked me several questions, and let me ask questions.

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at Apple (Cupertino, CA).

    Interview

    Two Skype interviews and they flew me in for on-campus interview. The apple travel services was very convenient. Two of the interviewers had to leave on a last minute trip so I only had 6 people to interview.

    Almost everyone were nice and friendly, interview is very casual and comforting. People are super busy there and you can totally fell that they want to get out of this interview room and back to work.
    The interview goes to very basic physics questions. Don't waste your time preparing for a professional question.

    Difficult Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at Apple (Cupertino, CA).

    Interview

    I've dealt with three HR people from Apple and two were very forgetful and unknowledgable and were unprofessional at times and I paid for it. The good one prepared you as to who you were going to meet and did what they said they were going to do. Kept communication and time commitments.

    Interview Questions

    • Depends on the group but I observed several people asking other people for a question, brain teaser, to ask an interviewee. It was to gather knowledge it was just something to do to look like they prepared. They really didn't care, like their opinion didn't matter anyway. It was obnoxious.   Answer Question

    I applied through college or university. The process took 6+ weeks. I interviewed at Apple.

    Interview

    1 onsite at school, then 14 interviews onsite. Really put me through my paces, in everything from optimization all the way to doing heat transfer and dynamics problems as well as more generic questions. It was pretty fun! Definitely more exciting than some of the more generic and silly questions that we've been talking about.

    Difficult Interview

    Application

    I applied through college or university. The process took 3 weeks. I interviewed at Apple (Cupertino, CA) in February 2016.

    Interview

    I got contacted by a recruiter that I met at a career fair, and had a couple phone interviews. After two phone interviews with two people on the PD team, I did not end up getting another round. I was not prepared for the questions they were going to ask me. I definitely should have prepared more because they try to stump you. They asked me some behavioral questions like what are your 3 biggest weaknesses as and engineer, as well as hard technical ones that I could have answered by reading off a table from a textbook. In fact, I indicated that I could look it up, and got scolded as I was informed that that was not the point of this technical interview. So word of advice: Ask politely before any technical questions if its okay to look something up, or just don't look stuff up. The advice that I got from them afterward was that they just want to see my process, so always explain your thoughts.
