Candidate reports for Google's ML Engineer role describe a loop that mixes coding, ML fundamentals and resume-driven ML depth, followed by a team-matching stage that several candidates found slower than the interviews.
One candidate was told by the recruiter to expect one LeetCode-style coding interview plus an AI/ML deep dive. That candidate prepared fundamentals such as bias-variance tradeoffs, evaluation metrics, gradient descent and regularization, and practiced implementing k-means or logistic regression from scratch. They also prepared for a lightweight question on deploying and serving a model, and noted that domain-focused interviews such as recommendation or ranking may include a system-design component. Another candidate was asked how a for loop works in assembly before a coding question, so a quick refresh of low-level performance basics may be worthwhile.
Depth matters. One candidate had an ML domain round anchored on a single resume project, covering technical decisions, the underlying math, complexity and communication. Prepare every meaningful resume bullet as a possible deep dive, and be ready to discuss your specialization honestly, since interviewers may steer the conversation toward their own interests.
Leveling and matching were the main frustrations. One candidate was downleveled from L5 to L4 after the phone screen, so be ready to discuss level early. Two L4 candidates who passed the loop described waiting on team matching, and one said the recruiter's home organization limited which teams made contact. Be ready to map your ML experience concretely to a team's needs, and ask your recruiter exactly where you stand in the approval process.

Synthesized from candidate reports. Individual experiences may vary.
One candidate's recruiter outlined what to expect, including an AI/ML deep dive and a LeetCode-style coding interview. Another candidate says a level discussion happened after the phone screen, including a downlevel from L5 to L4, so it may help to be ready to talk about level early.
One candidate mentions a phone screen before the onsite. In another interview, a candidate was asked how a for loop works in assembly before moving to a LeetCode-style coding question. Experiences likely vary by interviewer and team.
Candidates describe a mix of coding and ML depth rather than a fixed template. Reported content includes an AI/ML deep dive, preparation for implementing ML concepts from scratch, and a domain round anchored on a resume project. One candidate notes that domain-focused interviews may include system design. Content depends on the interviewer.
Two L4 candidates report passing the interviews and then waiting on hiring committee review and team matching. One had several match calls with long waits, and another saw match requests only from the recruiter's home organization. Timing is unclear, so ask your recruiter where you stand.
