Interview Prep Hub

Smart Contract Security Engineer

Senior-level interview prep for protocol-security roles owning the full security lifecycle — formal verification with Certora / Halmos, in-house security review, bug-bounty triage and war rooms, attack-vector research, and shipping safer Solidity faster.

If you only have an hour

Open 00-START-HERE first. Then drill 15-interview-questions with drill mode on. Reread 16-day-of the morning of.

Section A · Orient
00Start Here Master index, study schedule, key reframes. 01The Role, Decoded JD breakdown, stack purpose, constraints, what to ask them. 02Positioning From Scratch Mindset before content — how to interview honestly when you're light on direct on-chain experience.
Section B · Technical Core
03Core Fundamentals Foundational technical concepts this role demands. 04Deep Dive — Primary Topic The single most important technical area. Critical 05Deep Dive — Secondary Topic The second pillar interviewers will probe. 06Applied Patterns Production patterns and how they show up in interviews. 07Evaluation & Quality How you measure correctness, gas, and safety. Critical 08Error Handling & Failure Modes Attack vectors, edge cases, what goes wrong, how to detect it. Critical 09Governance & Audit Audit lifecycle, governance patterns, upgradeability, on-chain incident response. Critical
Section C · Coding
10Coding Fundamentals Solidity idioms, EVM mental model, Foundry workflow, fixed-point math, DSA patterns. 11Coding Problems Worked Hand-picked Solidity problems with multiple approaches and drill mode. Drill mode
Section D · Production
12Data & Pipelines On-chain data, subgraphs, indexers, oracles, off-chain monitoring. 13Deployment & Ops Foundry scripts, CREATE2, multi-chain deploys, verification, monitoring, on-call.
Section E · Reference & Execution
14Domain Context Smart contract security, formal verification, audit lifecycle. Vocab so you don't sound lost. 15Practice Interview Questions Drillable Q&A across all sections.

Study Paths
If you have 7+ days
  • Day 1: 01, 02 (orient) → 03 (fundamentals)
  • Day 2: 04, 05 (the two deep dives)
  • Day 3: 06, 07 (patterns + evals)
  • Day 4: 08, 09 (attack vectors + audit lifecycle)
  • Day 5: 10, 11 (Solidity drill on a timer)
  • Day 6: 12, 13 (data + deployment)
  • Day 7: Drill 15. Read 14 and 16. Sleep.
