9 reasons why

Adaface JSON Assessment Test is the most accurate way to shortlist 软件开发人员s

Reason #1

Tests for on-the-job skills

The JSON Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

了解JSON语法和结构的基础知识
解析和操纵JSON数据的能力
JSON模式验证的知识
具有序列化和挑选JSON的经验
了解JSONP和CORS概念
处理嵌套的JSON结构的能力
JSON Web令牌知识（JWT）
熟悉JSON-RPC协议
与RESTFUL JSON API合作的经验
使用JSONLINT等工具来验证和格式JSON的能力

Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

这些只是我们库中有10,000多个问题的一个小样本。关于此的实际问题 JSON测试将是不可行的.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment JSON测试 in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the JSON测试 from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

About the JSON Online Test

Why you should use Pre-employment JSON Test?

The JSON测试 makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

了解和使用JSON数据结构
解析和操纵JSON数据
创建和修改JSON对象
验证JSON数据
序列化和应对json

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the JSON Test?

测试自动化
测试自动化是指使用的过程自动化工具和脚本以执行有关软件应用程序的测试。它涉及编写代码以复制手动测试用例并自动执行它们，从而更快，更可靠的测试。测试自动化是在此测试中衡量的一项至关重要的技能，因为它通过验证其功能并确定任何潜在问题或错误来确保评估平台的效率和准确性。
数据操纵</h4> <p >数据操作涉及用于修改，转换和分析数据的技术和操作。该技能包括理解和应用各种编程概念和功能来处理和操纵数据，例如过滤，分类，加入和汇总。数据操作是在此测试中衡量的一项重要技能，因为它评估了候选人使用JSON数据，执行数据转换并从提供的数据中提取有意义的见解的能力。</p> <h4>错误处理
错误处理是指实施的策略和实践来检测，处理和解决程序执行过程中发生的错误或异常。该技能涉及了解不同类型的错误，识别潜在的错误来源，并实施适当的错误处理技术，以确保优雅的降级并保持软件的稳定性和可靠性。在此测试中测量错误处理有助于评估候选人编写健壮和耐受耐受代码的能力，从而提高评估平台的整体质量。
