Typically 8-12 years, but competency-gated, not tenure-gated. The bar shifts from execution to influence. System design and behavioral now share top weight. Writing rounds appear. Cross-team scope is the table stakes.
Drive technical direction across teams, de-risk big bets, and create leverage without authority.
Salary is approximate market context, not a promise. It varies a lot by country, company, and year.
Can you actually do this?
If one makes you hesitate, that is the gap. Open it to go learn it.
1-2 rounds. Multi-system, multi-team scope. Cross-team consistency, migrations, evolution over years.
Read someone else's design and critique. Spot risks, missing failure modes, trade-offs they skipped. Common at Meta, Stripe, Datadog.
2 rounds typical. Cross-team initiatives, mentorship, hiring stories, strategic disagreements. Roughly equal weight to system design.
Common at Meta (writing exercise), Stripe (memo), and AI labs. 30-60 min to write a memo arguing for a technical direction.
Lighter than Senior. Often 1 round, often practical (not LeetCode-style), and sometimes a low-level-design round instead. Some loops skip it entirely.
1-2 rounds. At Staff, this is half-behavioral and half-team-strategy. Bring real questions about org direction.
If team is infra, AI, ML, or security focused: deep domain round. Otherwise rare.
| Round | Tested? | Weight | What to expect |
|---|---|---|---|
| System Design at scope | yes | high | 1-2 rounds. Multi-system, multi-team scope. Cross-team consistency, migrations, evolution over years. |
| Architecture Review | yes | high | Read someone else's design and critique. Spot risks, missing failure modes, trade-offs they skipped. Common at Meta, Stripe, Datadog. |
| Behavioral (Staff) | yes | high | 2 rounds typical. Cross-team initiatives, mentorship, hiring stories, strategic disagreements. Roughly equal weight to system design. |
| Technical Vision / RFC | sometimes | high | Common at Meta (writing exercise), Stripe (memo), and AI labs. 30-60 min to write a memo arguing for a technical direction. |
| Coding / LLD | yes | medium | Lighter than Senior. Often 1 round, often practical (not LeetCode-style), and sometimes a low-level-design round instead. Some loops skip it entirely. |
| Hiring Manager | yes | high | 1-2 rounds. At Staff, this is half-behavioral and half-team-strategy. Bring real questions about org direction. |
| Domain Round | sometimes | varies | If team is infra, AI, ML, or security focused: deep domain round. Otherwise rare. |
The Staff bar is cross-team influence and judgment at multi-quarter scope. Many candidates accidentally study Principal content and run out of time on Staff fundamentals.
Design for evolution. Multi-region, multi-tenancy, migration paths. Trade-offs that play out over years.
Cross-team initiatives, mentorship stories, hiring, strategic disagreements. The bar is influence without authority.
Reading and writing ADRs. Critiquing other people's designs is its own skill at Staff.
Internal dev platforms, golden paths, paved roads. Trade-offs of platformization.
Postmortem culture, SRE patterns, debugging at scale. Required for any senior infra-flavored role.
The signature topics: RFC writing, technical strategy, cross-team leadership, hiring stories.
Most Staff+ loops now include some AI angle. Know LLM fundamentals, inference serving, training, RAG at architectural depth.
Consensus, replication, ordering. Be ready to defend choices in design rounds.
Storage-engine and consistency trade-offs to defend in design: B-tree vs LSM, MVCC, replication, isolation levels. Matters most for data or infra-adjacent roles.
Save those stories for Principal. At Staff, multi-quarter team initiatives are the bar.
Principal+ topic. You may get asked about reorg execution, not reorg design.
One coding round, often practical. Pattern recognition matters more than speed.
Refresh, don't relearn. A few weekly problems on weak patterns is enough.
Know Amazon LPs / Meta Jedi at a passing level; don't memorize every word. Stories matter more.
At Staff, behavioral and architecture share the top weight. Spend most of your time on the Staff+ Interview Prep section and your story bank.
The signature topics: RFC writing, technical strategy, cross-team leadership, hiring. Built specifically for Staff loops.
Half of every Staff loop. Story bank takes weeks to build. Start week 1 and never stop polishing.
Still important. Focus on multi-team and multi-system scope, not single-service problems.
Read 15-20 ADRs. Practice writing one. Common round at Staff is critique-the-design.
Most Staff+ loops now have an AI angle. LLM fundamentals, inference serving, training, RAG, evals at architectural depth.
Internal platforms, golden paths. Common subtopic in design and behavioral rounds.
Postmortem stories are common in behavioral. Have 1-2 well-rehearsed incident stories.
Staff loops sometimes include a coding round, often practical, not LeetCode. Refresh weak patterns; do not grind from scratch.
Some Staff loops still run an LLD / OOD round. Practice 2-3 problems if your loop has one.
For data or infra-heavy loops: the storage-engine and consistency trade-offs you defend in the design round. B-tree vs LSM, MVCC, replication, isolation levels.
Assumes 8-10 hours per week alongside your job. Staff prep is longer because story bank, architecture review, and RFC writing each take real time.
Staff loops vary widely by company. Click through for full breakdowns including the writing round formats.
6-7 rounds: 2 coding, 2 system design (one is architecture review), 2 behavioral (Jedi), 1 hiring manager. Writing round is common.
6-7 rounds: coding (1-2), system design (2), behavioral (Googleyness), leadership, hiring committee. Cross-functional scope expected.
5-6 rounds, one of them a Bar Raiser. Heavy Leadership Principle focus. Writing exercise (the narrative memo). Hiring stories essential.
Practical coding, system design (multi-system), architecture review, behavioral (Operating Principles), writing memo round.
5-6 rounds: system design, architecture review, behavioral (leadership and impact signal woven through), VP/Director round.
Heavy on AI infrastructure system design, technical strategy, safety mindedness, alignment with the lab's mission.
