9 reasons why

Adaface Perl Test is the most accurate way to shortlist Perl开发人员s

Reason #1

Tests for on-the-job skills

The Perl 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:

能够编写高效和清洁的Perl代码
熟悉Perl语法和数据类型
熟练掌握控制结构（环，条件）
了解Perl正则表达式和模式匹配
有Perl文件处理（阅读，写作，操纵文件）的经验
了解Perl模块和软件包
理解面向对象的编程原理
能够使用Perl连接到数据库
对Perl Web开发概念的理解
精通Perl调试和错误处理

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 Perl在线测试将是不可行的.

🧐 Question
Medium Package: Destroy OOPs	Solve
What does the following Perl code print?
Medium Package: Use Base OOPs	Solve
What does the following Perl code print?
Easy Registration Queue Logic Queues	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Perl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 Perl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.

About the Perl Assessment Test

Why you should use Pre-employment Perl Online Test?

The Perl在线测试 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:

理解和应用PERL语法和数据类型
在Perl中实施控制结构
利用Perl中的正则表达式
在Perl中执行文件处理
在Perl中使用模块和包装
在Perl中应用面向对象的编程原理
在Perl中建立数据库连接
使用Perl开发Web应用程序
调试和处理Perl中的错误
处理Perl中的异常和错误

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 Perl Online Test?

PERL PERL PERL DERANSERAINS </h4> <p >正则表达式是Perl中模式匹配和文本操作的强大工具。评估候选人在PERL正则表达式中的技能衡量其编写和理解复杂模式，执行字符串替代并从文本中提取特定信息的能力。</p> <h4> perl文件处理
文件处理技能是对于诸如阅读和写入perl中的文件之类的任务至关重要。对Perl文件处理有很好了解的候选人将知道如何打开，读取，写入和关闭文件，以及处理这些操作期间可能发生的错误或异常。
Perl模块和包装< /h4> <p> perl模块和软件包允许程序员创建可重复使用的模块化代码。评估候选人对PERL模块和包装的了解确保他们可以正确组织代码，使用现有模块并创建自己的可重复使用组件，以更好地可维护性和可重复使用性。</p> <h4> Perl对象面向对象的程序</ H4> <p>面向对象的编程（OOP）是Perl中重要的范式，用于以对象的形式创建和组织代码，该代码封装了数据和行为。评估候选人在PERL OOP方面的技能涉及评估他们创建课程，定义方法，处理继承并应用OOP原则来解决问题的能力。</p> <H4> PERL数据库连接
PERL的数据库连接能力允许程序员与数据库进行交互，执行查询，检索或修改数据。在PERL数据库连接上测试候选人可以衡量其建立连接，执行SQL语句，处理交易并有效地与Perl应用程序中的数据库合作的能力。
Perl Web开发
Perl已广泛使用在Web开发中，诸如构建动态网站，处理形式数据以及与Web服务器进行交互之类的任务。评估候选人在PERL Web开发中的技能确保他们可以使用适当的框架和库，使用Web协议，处理会议，并使用Perl。 P>调试和错误处理技能对于在Perl代码中查找和修复问题并优雅地处理错误至关重要。在PERL调试和错误处理上测试候选人评估其识别和解决错误，有效使用调试工具的能力，并实施强大的错误处理策略以增强其代码的可靠性和可维护性。
