Apple ML Engineer interviews typically include an initial screen and hiring manager call, a live technical screen, and a broader panel loop covering ML fundamentals, coding, and sometimes system design; loop content varies by team.

Apple's ML Engineer interviews vary noticeably by team, so treat any single account as a directional map rather than a fixed script. In one detailed account, the process opened with an initial screening and a hiring manager call. That call focused on the candidate's resume, past ML/AI projects, and why they wanted the role, and the manager also introduced the team. Another candidate, who received an offer, described a manager phone screen that paired behavioral questions with general technical concepts drawn from the job description.
The technical screen in that first account was a roughly 30-minute live NLP coding task with a staff engineer, plus resume questions. No hints were given and no internet access was allowed. Practice short coding exercises without outside references, and narrate your reasoning out loud as you work.
Accounts of the fuller loop differ: a full-day remote onsite with around eight interviewers, a five-panel loop, and a seven-round process spread over several weeks. Reported content includes:
One candidate noted that the recruiter's written outline did not match the actual interviews, so ask for team-specific expectations where you can. For one candidate, the final round with a skip-level manager was a deep dive into a recent project. It covered design trade-offs and what they would do differently, so prepare that story in depth.

I'll give you the outcome first since that's what most people scroll for: no offer. I still think of the process as a positive experience, even though it was one of the harder loops I've been through. There were six rounds in total, and the mix is what caught me off guard.
Two of the rounds were one-hour coding sessions, and they tested different things. The first was algorithmic coding problems. The second was a machine learning coding problem. If you've only drilled LeetCode-style questions, the ML round is the one that will expose gaps in your prep.
System design came up more than once. One round was a standalone system design interview, and two other rounds combined discussion of my past projects with system design, so I was walking through work I'd already done and then being pushed on how I would design things differently or at larger scale. Be ready to explain the architecture of your own projects in depth, including the tradeoffs you made and what you'd change now.
The last round was behavioral. It felt lighter than the technical rounds, but I wouldn't treat it as a warm-up. Have specific stories ready from your projects.
I didn't get an offer. The bar felt high across both classic coding and applied ML, and the system design expectations applied to my own past work as much as to hypothetical problems.
Prep tip from this candidate
Prepare for both LeetCode-style and ML-focused coding, since the coding format appears to vary by team and interviewers may freestyle it. Also be ready to go deep on the architecture and tradeoffs of your own past projects, because several rounds centered on them.

Synthesized from candidate reports. Individual experiences may vary.
One detailed account describes an initial screening followed by a hiring manager call. That call covered behavioral questions, a walkthrough of ML/AI projects, and motivation for the role, and the manager introduced the team. Another candidate described a phone screen with their manager covering behavioral questions and general technical concepts tied to the job description.
In one account, a roughly 30-minute technical screen with a staff engineer paired resume questions with an NLP-focused coding task. No hints were given and no internet access was allowed. Prepare to solve a short problem live without outside references and to explain your approach as you go.
Candidates describe a longer loop: a full-day remote onsite with around eight interviewers in one account and a five-panel loop in another. Reported content includes questions on ML approach, large language models, pandas, and AI project experience, plus some coding. Another candidate's seven-round process covered ML fundamentals such as the bias-variance tradeoff, API maintenance and design patterns, a keyboard application system design, and coding. One candidate noted the recruiter's template did not fully match the actual interviews.
One candidate who received an offer described a final round with a skip-level manager. It was a deep dive into their most recent project: not just what was built, but the design decisions, trade-offs, and what they would do differently. That candidate said the round felt more like a technical discussion than a standard interview. It followed five earlier rounds covering coding, ML fundamentals, API/design patterns, and system design over several weeks.
