Apple Software Engineer interview questions

Recruiter cold call, then onsite interview for a day. The day had 3-4 interviews and one of the interviews was with a panel of developers where they interviewed together.

Applied at an Apple booth set up at my university during a hackathon. A week later (in Nov 2015), I got a mail asking for an interview with the Siri team (had applied specifically to AI based roles). Was delighted and sent in the details like availability, phone number, etc. After that, there was no response from my recruiter. Three weeks passed by and I mailed her and I got an automated reply informing that she had gone on a month long vacation and was asked to contact another recruiter. Contacted him and he finally fixed a date for the interview. It never happened. He scheduled and rescheduled and it never ever happened. I was asked to contact my initial recruiter once she gets back from her vacation. I contacted her in early Jan 2016 and she replied a week later informing that the interview will not be happening as someone else got the role. I lost my chance at Apple because a recruiter did not check her mails properly. It is fine if they overlook mails from candidates who are asking for an interview. Once she has given a chance to a candidate, she must be responsible enough to make sure the candidate goes through the process. Extremely disappointed with how the recruiter corresponded with me.
