Smart Contract Interview Prep Hub (US-style loops, take-homes, security + proof)
Prep for smart contract interviews with real hiring signals: US-style rounds, take-home red flags, security thinking, and proof-stack examples that improve shortlists.
Most smart contract interviews don’t fail because of “lack of Solidity syntax.”
They fail because candidates can’t show
(a) reasoning under constraints,
(b) risk awareness,
(c) proof of shipping/testing, and
(d) clarity when explaining tradeoffs.
This hub is a map of what actually gets tested.
The typical loop (what to expect)
Quick screen (concepts + judgement)
Deep dive (design + security thinking)
Practical (testing, debugging, production readiness)
Team fit (how you work, not “vibes”)

US-style interview loops (what feels “different”)
If you’re targeting US companies: responses are usually judged on speed + clarity + structured thinking.
The winning move is: narrate decisions, name tradeoffs, and anchor with proof (repo/writeup).

Take-home assignments: green flags vs red flags
Green flags: timeboxed, clear evaluation, review conversation.
Red flags: huge scope, unclear ownership/IP, “ship production feature for free.”
A good “risk thinking” question to practice:

Security-first questions (that show real maturity)
When should you shift into “security mindset”?

STAR + proof-stack (for people who freeze in interviews)
STAR can work — but only if you anchor with measurable proof.

Production readiness (rare signal, huge advantage)
Incident thinking + monitoring stories stand out fast:

Want feedback?
Post your target role + level + 2 proof links + what you struggle with (screens / take-home / security / comms).
Want speed?
Audit / Rewrite helps fix proof positioning + interview narrative in 1 pass.
Closing question
What part of smart contract interviews feels most unfair: screens, take-homes, security depth, or “explain your project” rounds?
