9 reasons why

Adaface T SQL Test is the most accurate way to shortlist T-SQL计划分析师s

Reason #1

Tests for on-the-job skills

The T SQL 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:

能够编写有效的T-SQL查询的能力
能够设计和标准化数据库
在使用存储程序，触发器和视图方面的工作经验
精通数据操纵
能够利用索引来优化查询性能
了解SQL中的交易管理

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 T SQL在线测试将是不可行的.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment T SQL在线测试 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 T SQL在线测试 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.

SQL查询优化
索引策略
使用T-SQL进行数据操作
处理存储程序
了解触发器及其应用
创建和管理数据库视图

What topics are covered in the T SQL Online Test?

数据库设计
数据库设计涉及创建一个结构化框架，以在数据库系统中组织数据。它包括定义表，建立关系并确保数据完整性。衡量此技能很重要，因为它评估了候选人设计有效且可扩展数据库的能力。
sql查询
sql查询是用于从数据库中检索特定数据的语句。它们使用户能够根据特定标准过滤，排序和组合数据。评估此技能有助于评估候选人在构建复杂查询中的熟练程度，从数据库中提取相关信息。
索引
索引是数据库结构，可以通过更快的数据检索来提高查询性能。它们有助于根据指定的列快速找到数据。衡量此技能至关重要，因为它决定了候选人对通过创建索引和用法优化数据库性能的理解。
数据操作
数据操作涉及在数据库中修改数据，例如插入，例如插入数据库中的数据更新和删除记录。它需要了解SQL语句和数据库操作的知识。评估此技能有助于衡量候选人在保持数据完整性同时准确操纵数据的能力。
存储过程
存储过程是可以重复执行的数据库程序。它们增强了数据库性能，封装复杂的逻辑并促进代码可重复性。该技能对于衡量非常重要，因为它反映了候选人在创建有效且可靠的数据操作和检索过程中的熟练程度。
触发器
触发器是数据库对象，当时是在自动执行预先定义的动作的数据库对象。发生特定事件。它们允许用户执行数据完整性并实施业务规则。评估此技能有助于评估候选人对触发创建的理解及其设计有效机制以实施数据一致性的能力。
视图
视图是根据查询创建的虚拟表，这些表从查询中简化了数据检索，提供数据的逻辑表示。它们使用户能够提取相关信息，而无需直接访问基础表。衡量此技能至关重要，因为它证明了候选人创建有效且可重复使用的视图以简化数据访问的能力。
归一化
归一化是以逻辑和高效的方式组织数据的过程通过减少冗余和依赖性。它涉及将数据分解为多个表并建立它们之间的关系。评估此技能很重要，因为它评估了候选人对数据库归一化原则的理解及其设计结构良好的数据库模式的能力。
交易
交易确保数据确保数据的完整性和一致性通过将多个数据库操作分组为单个原子单元将数据库分组。他们保证，如果发生错误，交易中的所有操作都会成功执行或回滚。衡量此技能至关重要，因为它证明了候选人对数据并发，一致性和恢复的理解。
