    Difficult Interview

    Application

    I applied online. I interviewed at Apple (Mountain View, CA) in November 2015.

    Interview

    2 stages of phone calls (one HR, one more technical), then a facetime interview with the hiring manager. I was then invited for an onsite interview (which required them to pay for airfare, hotel, and per diem). The onsite interview was all morning long and I met one-on-one with 4 or 5 separate engineers.

    Difficult Interview

    Application

    I applied through an employee referral. The process took 1 day. I interviewed at Apple in January 2014.

    Interview

    I was notified a day in advance for a phone interview for what I believed was the Acoustic Calibration & Instrumentation Engineer position. I had friend at Apple give an inside referral and the interview ended up not even being for the specified position. It was just to see if I would be eligible to join the team. The interview felt like a final exam that dug into deep technical questions about DSP fundamentals and C++ topics.

    Average Interview

    Application

    The process took 1 day. I interviewed at Apple (Cupertino, CA) in May 2012.

    Interview

    First I was called by Recruiter. They found me Through Linkedin. They set up a phone interview. Then a technical Quiz. And then they invite me on site. I was supposed to have interview with 8 people. I was late because of the flight delay. I was interviewed by just one Idiot guy. He did not know any thing about Hardware. He told me they are not going to continue interviewing. He told me I was not a good fit and asked me to leave. I did not expect such a large and famous company acting like a child. This was an experience for me to make sure whoever ask me onsite interview they know who they are looking for. I am designing hardware everyday in my current job.

    Application

    I applied through a recruiter. The process took 1 day. I interviewed at Apple in June 2010.

    Interview

    This was just a preliminary 1 on 1 interview at Apple's Cupertino campus. The hiring manager had to phone someone else to interview me because he couldn't make it. That person didn't seem prepared at all. Overall not a good experience, and I didn't get selected for the next round.
