Candidate interview experiences
First-hand accounts from people who interviewed at Apple.
Stability Engineer
The interview process for the Stability Engineer role at Apple started with a recruiter reaching out to set up a 30-minute Webex call with an engineering hiring manager. During this call, they asked both behavioral and technical questions centered on my experience designing and optimizing scalable data pipelines, working with large-scale streaming and batch data, and making sure systems were fault-tolerant and reliable. They also dug into my familiarity with distributed systems, cloud platforms, and programming in Python and Java.
- They asked me to talk about a time I built or improved a data pipeline to handle large-scale, real-time data, and wanted to see how I approached stability, performance, and fault tolerance.
- They asked about my background designing and tuning scalable data pipelines.
- They asked how I’ve dealt with large-scale streaming and batch data.
Engineer
The interview process has five rounds, each 30 minutes long. The hiring manager asks detailed questions to check the candidate’s expertise, problem-solving ability, and hands-on knowledge for the role. If you get an offer, HR will then ask you about your salary expectations.
- Why should we choose to hire you?
Product Engineer
Got interview scheduled with project manager. He didn't come to the interview. I mailed HR and rescheduled again, interviewer came 10 mins late and didn't even apologize. He asked a couple of technical questions and was behaving like not interested in interviewing (looking somewhere else, yawning and all when I'm explaining). Just don't take interview if you are not interested. You are just another company on this planet. Respect jobseekers. Not gonna accept even if I get an offer.
- Can you tell me about yourself
- Can you talk about your projects
