9 reasons why

Adaface SOLID, Technical Aptitude & Coding Test is the most accurate way to shortlist 软件工程师s

Reason #1

Tests for on-the-job skills

The SOLID, Technical Aptitude & Coding Online 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:

理解和应用坚实的原则
设计和实施面向对象的设计概念
证明解决问题的技术能力
使用各种数据结构
编写干净可维护的代码
理解和实施设计模式
有效处理异常和错误
优化性能代码
使用关系数据库
有效地使用版本控制系统

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。关于此的实际问题固体，技术能力和编码测试将是不可行的.

Medium Rewards Activities Order Database Connection	Try practice test
A new popular app tracks the activities performed by its users and grants them rewards based on each individual's total activities performed in a year. This data is maintained in a database table (activitesinfo), with the following columns: userid, totalactivities, reward. This year, due to fundraising activity, the company has decided to further reward its users by enhancing the reward as per the following formula: If reward < = 4000, increase it by 2%, If 4000 < reward <= 8000, increase it by 4%, If reward > 8000, increase it by 6%. The tech team has written three different scripts to calculate increment for each slab, each script is to run as a separate transaction. Here are the three scripts: Script 1: For users with reward <= 4000, set reward = reward * 1.02 Script 2: For users with reward > 4000 and reward <= 8000, set reward = reward * 1.04 Script 3: For users with reward > 8000, set reward = reward * 1.06 Each script is to be executed separately. Which of the following options will update the rewards as expected: A: Execute Script 1 followed by Script 2 followed by Script 3 B: Execute Script 2 followed by Script 3; Script 1 running concurrently throughout C: Execute Script 3 followed by Script 2; Script 1 running concurrently throughout D: Execute Script 3 followed by Script 2 followed by Script 1 E: Execute Script 2 followed by Script 3 followed by Script 1

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment 固体，技术能力和编码测试 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.

What topics are covered in the SOLID, Technical Aptitude & Coding Online Test?

固体原理
固体原理是面向对象的编程中的五个设计原理，旨在使软件系统更可维护和扩展。它们包括单个责任原则（SRP），开/封闭原则（OCP），Liskov替代原理（LSP），界面隔离原理（ISP）和依赖性反转原理（DIP）。通过衡量该技能，招聘人员可以评估候选人对这些原则的理解及其在软件设计中应用它们的能力。
面向对象的设计
面向对象的设计是一种编程范式，将软件应用程序组织到具有状态，行为和身份的模块化组件中。它促进代码可重复性，可维护性和可伸缩性。衡量此技能有助于招聘人员使用面向对象的编程原理来评估候选人在设计软件系统方面的熟练程度。
技术能力
技术能力是指候选人理解和应用技术的能力解决问题和决策方案中的概念和原则。它涉及逻辑推理，分析思维，对细节的关注和解决问题的能力等技能。在此测试中评估技术才能使招聘人员可以评估候选人的整体技术能力及其在技术角色中脱颖而出的潜力。
数据结构
数据结构是组织组织的基本构建基础并将数据存储在计算机内存中。他们提供有效的方法来执行搜索，分类和操纵数据等操作。衡量此技能使招聘人员能够评估候选人的知识和能力，以选择适当的数据结构，以解决有效的算法解决问题和软件开发。
