## SWE / Data / Infra loop

A typical full-time pipeline runs **recruiter intro → phone screen → onsite (4–5 rounds) → offer**, with end-to-end timing around 6–8 weeks. Rescheduling between rounds is common and onsite slots are frequently split across days; budget a multi-week onsite window rather than a single block.

- **Recruiter intro (30 min)** — background, target team, comp range, process overview. Principal/Staff candidates may be asked role-specific domain questions (e.g. fraud, ads) directly in this call.
- **Phone screen (45–60 min)** — single coding round in the candidate's preferred language. The rate-limiter problem dominates this slot; runners-up are the function-call-path coding problem and a like-button system design (when the recruiter routes to a phone-SD instead of phone-coding). Hidden test cases run automatically on submission; passing all visible cases is not enough.
- **Onsite loop (4–5 rounds, virtual or in-person)** typically combines: one coding round, one or two system-design rounds (regular SD + product/feature SD), an HM behavioral round, and a director or staff/principal culture round. Senior+ candidates are split into a regular SD and a deep-dive on a prior design.
- **HM / director rounds** are scheduled last and are explicitly weighted; multiple candidates have reported strong technical performance but a non-aligned HM/director chat tipping the loop to a reject.

## Recruiter pre-loop call

A growing number of candidates report a 20–30 minute pre-onsite call with the recruiter that walks through the loop slot-by-slot, names the interviewers, and previews the format of each round (sometimes including the prompt family). Use it aggressively: ask which SD theme each interviewer typically picks, and ask whether the HM has a specific signal axis to brush up on.

## After the onsite

Decision turnaround is fast — most candidates hear back within 2–7 days. Detailed feedback is not provided on rejection; a follow-up recruiter call is sometimes available but is not a debrief. Down-leveling to a more mid-level role can be requested proactively if a single round felt weak, but is rarely granted retroactively.

## Frontend (UI) loop

Frontend-specialized candidates run a UI-flavored variant of the same pipeline: a phone screen (the function-call-path coding problem and rate-limiter still appear here), then an onsite of **frontend coding + frontend system design + HM behavioral**. The system-design slot is a frontend SD prompt (image feed, feed-status app, notification UI). At staff / principal level the frontend SD interviewer will drill well past the component tree into backend delivery detail — e.g. a "real-time notification system" prompt that turns into fan-out, push transport, and delivery-guarantee questions. Prepare the backend contract behind your UI, not just the rendering layer.

## Frontend / Fullstack matching wrinkle

Frontend-labeled openings can still route fullstack candidates through a frontend-heavy onsite, then switch to team matching if the hiring manager feels the prior experience is too backend/fullstack for the original team. A strong technical onsite is not always enough to close the loop; final matching and executive conversations can still reject on ownership posture or career-decision signal.

## Frontend screen variant — 2026 Q3

Frontend candidates may instead receive a **45-minute first technical screen** built around implementing a real-world UI component with state and user-event handling. TypeScript, JavaScript, and React are accepted choices. Recruiters may disclose this format during the intro call, so confirm whether the screen is UI implementation or the general coding rotation before choosing a preparation track.

## Vanilla frontend variant — August 2026

A senior frontend phone screen may require a browser widget built in vanilla HTML, CSS, and JavaScript, with frameworks and third-party libraries explicitly disallowed. Expect held-state behavior, physical-keyboard events, mouse events, and simultaneous inputs to be part of the evaluation. Confirm the allowed frontend stack before the interview rather than assuming React or TypeScript is available.

## Fast team-specific MLE loop — August 2026

A senior MLE team can run two first-round conversations followed by a four-round virtual onsite. The first wave combines a 60-minute project presentation with a 45-minute HM conversation. The onsite then covers practical ML modeling, one CodeSignal coding round, a second HM conversation, and a director calibration round; the four slots can be split across two days. Scheduling and decisions can move unusually quickly, including onsite scheduling within days and a verbal offer on the next business day.

MLE / Research NG Loop

Roblox interviews lean heavily on a small, stable repertoire of coding and system design prompts drawn from the company's own product surface — rate limiting, like-button counters, matchmaking queues, delayed payments. The bar is high but predictable: interviewers want bug-free implementations with crisp boundary handling and design discussions that ground every trade-off in real platform scale (millions of concurrent players, hot creator experiences, cross-region latency). HM and director rounds heavily probe past experience with comparable traffic and scope.
