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.

    Interview

    I made it through two rounds, live coding and verbal questions. They were very helpful and made sure that all questions I had were answered. It was very interesting to see how such a vig company was able to make the process so personal. It really made me want to work there!

    I applied through other source. The process took 1 day. I interviewed 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.

    Difficult Interview

    Application

    I applied online. The process took 6 weeks. I interviewed at Apple (Cupertino, CA) in August 2015.

    Interview

    I applied online through the Apple jobs website. I was contacted the following day by a recruiter and set up an initial call for that week. After the initial phone screen with the recruiter about my background and interests, I moved to the technical phone screen portion of the interview. This interview was FANTASTIC compared to most tech companies. I felt like the interview was more of a technical discussion about real software engineering problems than a straight "code this" kind of interview. Towards the end, I was asked to describe how I would solve two different problems but it was just conceptual, no coding. I found out the next day that I made it to on-site interviews. Onsite I had 4 one hour interviews, with 2 interviewers in each one. Meeting a total of 8 people was a lot but gave me a good feel for the team. Later that week, the recruiter contacted me and told me the team wanted to do one more technical interview over the phone. This last interview was a traditional coding interview you see at other companies. Two days after this, I was contacted and told I would be receiving an offer.

    Interview Questions

    • On-sites consisted of two coding questions, one database design question, and one networking question.   Answer Question

    Interview

    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.

    Interview

    This was by far the worst interview process I had ever experienced. I applied online and was contacted by a recruiter for a specific role. She never contacted me back to set up a time but later that week an engineer called me and was under the impression our interview was confirmed for that time. I was completely unprepared and so I told him that the recruiter hadn't set up a time but he gave me the impression that once it was confirmed with him he couldnt reschedule so it was either then or never. I went through the interview but wasn't ready and did not perform very well not surprisingly.

    I applied through a recruiter. The process took 3+ months. I interviewed at Apple (Cupertino, CA) in June 2015.

    Interview

    I was contacted by a recruiter, and then was interviewed at Cupertino. The position I applied was highly related to my current job. The interview process was going well until the last round of on-site. I was interviewed by 8 persons for a whole day, and the interviewing panel was severely in lack of diversity. Apart from the HR lady who was White, all engineer interviewers were Indian. Half of them were nice and the other half were hostile. I am not Indian and they didn't like me. Regarding the un-friendly ones, I could feel that they just wanted to bring me down when they entered the room. I was in a technical interview for a future job. However, these interviewers treated me as a Customer support engineer sent by my current employer company to service Apple. They asked me many BS questions like "how is XXX feature implemented" and then blame me that something was poorly implemented and why it was the case. Oh man, I am not the architect for those features, blaming me couldn't help anything! Oh yes, blaming the interviewee gave the Apple interviewers a great sense of accomplishment, that Apple is greater than anyone else on this planet! When it was my turn to ask questions to them, oh sorry, the spirit of keeping things secret is in the bone of Apple's culture, nothing could be discussed. I have to say that interviewing with Apple is BORING, because I have to answer a lot of BS questions and get blamed for nothing, while I couldn't ask any technical question about Apple at all because everything is secret. Given that Apple's interviewers are so ignorant, so rude, and are in lack of diversity, I will not apply for any job at Apple in the future.

    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.
