Interview

Around 2 months after I submitted my resume for Apple software engineer position, I got a call from the hiring manager. He asked me what was the good day for the interview. It took half day for meeting 5 people. It was long hour interview for me. Each interviewer spent ~ 30 minutes and asked ~ 4 questions. Each interviewer asked questions in the different areas.

    I applied through other source. The process took 1 dayinterviewed at Apple (Cupertino, CA).

    Interview

    I was expedited through the process as Apple acquired the company I was going to work for. Apple flew me out for one day of on-site interviews, and I had three 2-1 interviews. There was no effort to get to know me in any of them. Each interview was an hour spent entirely on technical questions covering algorithms and system design. The first two interviews were not great, but not terrible. I asked a lot of clarifying questions, which seemed to annoy the interviewers more than anything. Weird. The worst interview I've ever had was the 3rd one, with the two team leads. One of them wrote up a problem on the whiteboard, and then spent the rest of the interview looking bored out of his mind at his phone. His problem was very vague and incomplete as he first asked it, and when I asked questions about it he got frustrated and talked down to me. He would occasionally glance up at my progress (it wasn't a hard problem once the details were worked out) and make a snide remark about what I had written. He expected syntactically perfect whiteboard code, and threw in some expletives for an added bonus. The other interviewer would snicker whenever the first criticized my code. At the end they asked if I had any questions, but every question I asked was met with, "That's confidential." It was definitely the most unprofessional interview I've ever been a part of, and I almost walked out of it because it was clear it was wasting all of our time. Unfortunately the misery didn't quite end there, as it took Apple three full months (and 13 reminder emails) to reimburse me for the costs I had to pay for cab rides and per diem expenses. I was also never reimbursed for a flight I had to cancel because of the interview timing, but at this point I'm just tired of dealing with them. If possible, try to get Apple to pay up front for as much stuff as possible, because the reimbursement process is a nightmare. My (senior) recruiter had no idea where to even begin with it, which I still don't quite understand.

    On site interview from 10 AM to 5 PM. In total there were about 6 interviews for an hour each, and an hour lunch at 1 infinite loop. Interviewers were very fair and had a conversational demeanor. Apple paid to fly me out to CA and covered all of my expenses.

    Easy Interview

    Application

    I applied through an employee referral. The process took 4+ weeksinterviewed at Apple (Cupertino, CA) in June 2015.

    Interview

    Pros: Recruiters get in touch almost immediately. You can interview with multiple teams at once ..independently ..uh well, read cons below. Response time is almost always good. Cons - welcome to reality: I had couple of phone interviews with 2 of the teams and one with the third. Both interviews with the first 2 teams went way beyond excellent, with me answering every single question and having a good and engaging discussion with the interviewer. I am baffled at the outcome - rejected by both teams with no feedback. If they say background is not a fit after 2 rounds of interviews, I do not see why they even had to hold the 2 interviews. One team got back after first interview saying they want me to come onsite. After giving my availability and almost after 3 weeks, they get back saying they want another phone interview. I agreed. Almost immediately after the phone interview, I was rejected. It is not hard to connect the dots and see that they had made the decision already. Moreover, they asked for another round of interview after the first 2 team rejects. It is again not hard to see that, well, the process of multiple team interviewing is not independent. One team asked me to code in coderpad.io. The code I wrote was right but the interviewer only used c++ compiler. The same code worked perfect on C compiler. I sent a note after the interview. But guess what, reject anyway.

    I applied online. The process took 4+ weeksinterviewed at Apple (Seattle, WA).

    Interview

    I interviewed with the Seattle's new icloud team. Had a couple of phone interviews that were fairly standard, and was invited onsite to their temporary office. The first onsite interview was with the hiring manager. He was smug and had strong opinions about how variables should be named, the flow of the code etc. It almost looked like he made up his no-hire decision within a couple of mins of the interview and was spending the last hr trying to convince himself why his decision was right. Whatever questions I had was replied with "I can't disclose that information". I don't understand what the point of asking me If I had any questions was, if you're not going to answer anything. The other interviewers and the recruiters I dealt with were pleasant. Disappointing end since I really like apple, but i'd have hated working for that manager anyways.

    I applied through a recruiter. The process took 2 weeksinterviewed at Apple (San Jose, CA) in May 2015.

    Interview

    Recruiter invited onsite directly for a recruiting event. No phone screen. Meet 6~7 interviewer. The most impressive are the coordination of the seamless process. The recruiters make sure that you have a bathroom or water break between sessions. As a candidate I felt I was well taken care of. The hiring managers and engineers are also very well prepared, and they are all very passionate about what they are doing. It was a great experience for me although no offer in the end.

    I applied through other source – interviewed at Apple (Cupertino, CA) in March 2015.

    Interview

    I had two interview sessions in the morning -- I am not a morning person. One question pertained to tree traversal so it was basic CS. Not difficult but if you haven't memorized the routine you have to work it out on the fly. A decent question. Another question pertained to keeping a table of custom table view cells fully updated with images. Again not difficult as I've done this. Before arriving I was asked to write an app similar to what they produce, which was not difficult and took 6 hours. I'll be putting that a variant thereof in the App Store. Very little phone screening was required before the interview was set up, which was irksome as it suggests a "culture fit" is what they're really trying to assess. I'm a dude but if they don't hire me, I hope they'll hire a female programmer to add some diversity. Areas for improvement for Apple: 1. Don't assume everyone is a morning person :) 2. Do a couple technical interviews over the phone beforehand like Google does.
