9 reasons why

Adaface MS SQL在线测试 is the most accurate way to shortlist MS SQL数据库管理员s

Reason #1

Tests for on-the-job skills

The MS SQL在线测试 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:

能够编写复杂的SQL查询的能力
了解数据库设计原理
归一化技术的知识
有创建和管理索引的经验
熟练的桌子
在SQL中使用子征服的能力
了解数据库中的观点
熟悉存储程序
触发器的知识
了解SQL中的交易
优化SQL查询性能的能力
数据操纵的经验
在SQL中了解数据定义

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 MS SQL测试将是不可行的.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment MS SQL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 MS SQL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.

编写复杂的SQL查询
设计有效的数据库
应用归一化技术
优化数据库性能
有效地使用索引
利用各种类型的连接
创建和使用子征服
理解和处理观点

What topics are covered in the MS SQL在线测试?

数据库设计
数据库设计涉及创建数据库的结构和组织，包括表，关系和约束。确定候选人是否可以设计符合业务需求的高效和可扩展数据库是至关重要的。
归一化
归一化是在数据库中组织数据以消除冗余性的过程并提高数据完整性。评估此技能有助于确定可以设计适当归一化的数据库的候选人，从而减少数据重复并提高数据一致性。
索引
索引是通过启用更快数据来改善查询性能的数据库结构恢复。测量此技能确保候选人了解选择和创建适当索引以优化查询执行的重要性。
JONINS
加入加入来组合基于相关列的多个表中的数据。这项技能对于候选人来说至关重要，以证明写作的熟练程度加入语句并有效地从多个表中检索数据。
subqueries
子查询是SQL语句中的嵌套查询。评估这项技能有助于确定可以编写复杂查询并利用子查询的候选人从多个级别检索数据并获得所需的结果。
视图
视图是从一个虚拟表中创建的虚拟表询问。衡量此技能确保候选人可以有效地创建，修改和使用视图来简化复杂查询，增强数据安全性并提高查询性能。
存储过程
存储的过程已预编译SQL代码存储在数据库中，提供了执行复杂操作的方法。评估此技能有助于确定候选人是否可以在数据库中设计和编写有效的存储过程。对特定事件的响应，例如插入，更新或删除操作。此技能评估有助于确定可以设计和利用触发器来执行数据完整性，实施验证或自动化某些数据库操作的候选人。
交易
交易是由工作组成的逻辑单位，由工作单位组成多个数据库操作，确保数据一致性和可靠性。评估此技能有助于确定候选人是否了解交易的概念并可以有效地管理它们以维持数据完整性。
性能调整
性能调整涉及通过调整配置来优化数据库的性能，索引，查询和其他因素。评估此技能有助于确定可以从查询速度，资源利用和整体效率方面分析和改善数据库的候选人。
数据操作
数据操纵涉及修改使用插入，更新，删除和类似操作的数据库内容。衡量此技能确保候选人可以有效地操纵数据库中的数据，以确保准确有效的数据更新和修改。
数据定义
数据定义涉及定义结构，组织和属性使用创建，更改和删除语句的数据库中的数据。评估此技能有助于确定候选人是否可以准确定义数据库对象，例如表，列，约束和索引。
