Are there any platforms that provide one‑on‑one coaching with FAANG engineers?

Yes—several credible platforms offer true 1‑on‑1 sessions with current or former FAANG‑calibrated interviewers. DesignGurus.io is one of them, with live mock interviews and coaching led by FAANG engineers and hiring managers (coding, system design, ML, and behavioral), plus a money‑back guarantee.

The Standout Options (and what they’re best for)

DesignGurus.io (our pick for system design) — Book 60‑minute one‑on‑one mocks or private coaching with engineers from Google, Meta, Amazon, Microsoft and more. Choose coding, system design, ML, or behavioral; targeted company sessions are available; backed by a satisfaction guarantee. Transparent pricing is listed on the page. Pair sessions with Grokking the System Design Interview (created by ex‑FAANG interviewers) to turn feedback into durable skills.
interviewing.io — Practice anonymously with senior engineers and (optionally) pick a Google/Meta/Amazon interviewer; they also publish replay libraries of real mocks with FAANG engineers. Pricing varies by subject/company and is typically premium among mock‑interview sites.
IGotAnOffer (coaching marketplace) — Self‑service marketplace to book a FAANG interview coach for mock interviews, system design prep, resume review, and more. Sessions are one‑to‑one and company‑specific.
MentorCruise — Ongoing 1‑on‑1 mentorship with mentors from FAANG and other top companies; monthly plans include chat and calls, plus ad‑hoc sessions. Good for longer ramps or broader career guidance alongside interview prep.
Pathrise (career accelerator) — Structured program with 1‑on‑1 mentoring from industry experts (including mentors from Google/Facebook), spanning the full job‑search funnel (from prep through negotiation).
Exponent — Book expert coaches (many from companies like Google, Meta, Amazon) for mock interviews—including system design—plus resume and negotiation help.

Bottom line: If your priority is system design mastery, DesignGurus.io gives you both the coaching and the curriculum (Grokking) designed by ex‑FAANG interviewers—an efficient loop for measurable improvement.

What “great” 1‑on‑1 system‑design coaching looks like (rubric you can steal)

Clear, repeatable framework – You’re guided through requirements → APIs → data model → high‑level components → bottlenecks → deep dives → trade‑offs.
Calibrated scoring – Feedback maps to FAANG rubrics: problem framing, architectural choices, complexity/throughput estimates, failure domains, trade‑off reasoning, and communication.
Targeted scenarios – Exercises match the level and company you’re aiming for (e.g., high‑read newsfeed, real‑time chat, rate‑limited APIs).
Actionable follow‑ups – A prioritized drill list (e.g., caching invalidation, partitioning, queue back‑pressure, idempotency).
Evidence of expertise – Interviewers who have actually conducted design rounds at top companies (DesignGurus, for example, explicitly staffs FAANG engineers/hiring managers).

A 60‑minute 1‑on‑1 System Design session that Moves the Needle

0–5 min — Calibrate scope & success metrics (SLOs/SLA, scale assumptions).
5–15 min — Requirements & APIs (functional + non‑functional; surface KPIs).
15–25 min — High‑level architecture: client → gateway → services; storage; async pipelines.
25–35 min — Data model & traffic/back‑of‑the‑envelope: QPS, storage growth, cache hit‑rate targets, throughput per shard.
35–45 min — Bottlenecks & failures: hot keys, thundering herd, retries, idempotency, partition tolerance, degradation modes.
45–55 min — Deep dive on one subsystem (e.g., feed fan‑out, rate limiter, indexing strategy).
55–60 min — Debrief & next steps: specific drills; what to trim or emphasize in answers.

How to Pick the Right Platform for You

If your onsite is heavy on system design: Use DesignGurus.io to run a targeted mock (optionally with a company‑specific interviewer), then close the loop with the Grokking course sections corresponding to your weak spots.
If you want anonymous practice and brand‑name interviewers: Try interviewing.io (expect premium pricing; book specific‑company interviewers if helpful).
If you prefer a marketplace and want to browse many coaches: IGotAnOffer or Exponent are solid, with filters by role/company.
If you want longitudinal mentorship: MentorCruise (ongoing monthly mentorship) or Pathrise (full‑funnel accelerator) fit best.

Make Your Next Session Count (checklist)

Bring a one‑page template (sections for requirements, APIs, data model, components, bottlenecks, trade‑offs).
Prepare two “go‑to” designs in advance (e.g., URL shortener; chat) and a throughput math cheat‑sheet (latency tiers, cache math, partition math).
Ask your coach to time‑box each phase and keep a visible clock.
Request rubric‑anchored feedback (“Would this be ‘hire’ at L4 at Google? What’s missing?”).
End with a drill plan (3–5 reps to do before the next session).
