Smart Contracts Test
The Smart Contracts Test helps hiring teams assess intermediate blockchain candidates on Solidity basics, gas and storage decisions, and common security risks. It is suited to roles that write, review, or maintain Solidity code and need more than resume claims.
Summary of the Smart Contracts Test
The Smart Contracts Test helps hiring teams assess intermediate blockchain candidates on Solidity basics, gas and storage decisions, and common security risks. It is suited to roles that write, review, or maintain Solidity code and need more than resume claims.
3 dimensions, scored separately
Solidity basics
This measures knowledge of core Solidity syntax and behavior, including visibility, state mutability, and common coding patterns. It matters because developers need these basics to write correct contract logic and review code without introducing avoidable errors.
Gas & storage
This measures whether a candidate understands how storage choices and function design affect gas costs and contract efficiency. It matters at work because poor decisions here can make contracts expensive to use and harder to maintain.
Common vulnerabilities
This measures awareness of frequent smart contract security issues and the coding choices that help prevent them. It matters because even simple mistakes can expose funds, break contract behavior, or create audit findings later.
Everything about the Smart Contracts Test
Pair this test with the rest of the first round: springhire's candidate screening software adds a one-way video interview and resume scoring to the same candidate link, ranked in one report.
01What is the Smart Contracts Test?
This test checks whether candidates can reason through the practical choices involved in writing and reviewing Solidity code. It covers core language concepts, function visibility, state reads, storage behavior, gas-aware implementation, and common vulnerabilities that affect contract safety. Questions are built around realistic developer situations, such as selecting the right modifier for an off-chain read or handling a change from public to external when internal logic is still needed. The result gives hiring teams a focused signal on day-to-day smart contract knowledge, and Springhire uses it as an early screening step before live coding or technical interviews.
02How does the Smart Contracts Test work?
Candidates answer 20 multiple-choice questions in 10 minutes. Questions are drawn from a bank of 60, so each candidate gets a randomised set. The test is set at an Intermediate level, is auto-scored, and is designed to measure practical programming knowledge rather than broad blockchain theory.
03Why is the Smart Contracts Test important to employers?
Smart contract hiring carries a clear risk: a candidate may sound credible in interviews but miss basic Solidity rules, write wasteful code, or overlook common attack paths. This test helps reduce that risk early by checking whether candidates can make sound coding decisions before they move to expensive interview rounds.
How to interpret Smart Contracts Test results
Every candidate report scores each dimension separately. Here is what high and lower scores typically look like at work, and how to use them in your hiring decision.
Solidity basics
High scorers: A high score shows the candidate can apply core Solidity concepts correctly in common development scenarios.
Lower scorers: A low score suggests gaps in essential language knowledge that may slow delivery or lead to basic coding mistakes.
Gas & storage
High scorers: A high score indicates the candidate can make efficient implementation choices that balance correctness, cost, and maintainability.
Lower scorers: A low score suggests the candidate may write contracts that work functionally but waste gas or misuse storage.
Common vulnerabilities
High scorers: A high score shows the candidate can spot common security risks and choose safer contract patterns.
Lower scorers: A low score suggests the candidate may miss known vulnerability patterns and need close review on security-sensitive work.

Frequently asked questions
This test fits candidates for roles that write, review, or maintain Solidity smart contracts. It is best for intermediate-level hiring, where you need evidence of practical coding knowledge before interviews.
The test covers Solidity basics, gas and storage decisions, and common vulnerabilities. Questions focus on practical coding judgment, such as choosing the right function modifier or handling visibility changes correctly.
Use the score as an early screening signal, not as the only decision point. Strong results support moving a candidate into code review, pair programming, or a technical interview, while weak results can help you avoid investing more time too early.
The test is aimed at intermediate candidates. Junior candidates may find it challenging, while senior candidates should generally perform well if they have hands-on Solidity experience.
It is designed to measure practical knowledge used in day-to-day smart contract development. The questions focus on coding choices and security awareness rather than broad blockchain concepts or academic theory.
