Adaface 生锈在线测试 is the most accurate way to shortlist 生锈开发人员s



Reason #1

Tests for on-the-job skills

The 生锈在线测试 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:

  • 能够使用标准运算符和语法编写正确有效的生锈代码
  • 能够与枚举和在生锈中匹配的图案匹配的能力
  • 能够理解和利用生锈中的通用结构
  • 能够与Rust的智能指针合作
  • 理解和实施Rust中参考计数的能力
  • 能够在生锈中使用线程池和工人
  • 理解生锈的所有权概念
  • 能够使用循环和绳子在生锈的能力
  • 理解Rust中的OOPS概念
  • 能够与Rust中的通用迭代器一起工作
  • 理解生锈中的并发概念
  • 能够与Rust的线程一起工作
Reason #2

No trick questions

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.

Why we started Adaface
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 生锈在线测试 将是不可行的.

Review the following code and pick the correct statements:

A: The code prints 1223
B: The code prints 1111
C: The code prints 1234
D: The callPassedFunction(passedFunction) on line 7 makes a copy of passedFunction to become the argument of callPassedFunction. The copy gets executed and the x of copy becomes 2, but the original closure still holds a value of 1 for its captured x.
E: The callPassedFunction(passedFunction) on line 7 makes a copy of passedFunction to become the argument of callPassedFunction. The copy gets executed and x of the copy and the origin both become 2.

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

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 生锈在线测试 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 生锈在线测试 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.

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 生锈在线测试?

  • 枚举和模式匹配</h4> <p >生锈中的枚举和模式匹配是用于管理复杂数据类型并根据不同情况做出决策的强大工具。应衡量此技能以评估候选人使用枚举类型和模式匹配结构在生锈中使用和操纵数据结构的能力。</p> <h4>通用结构

    通用结构使开发人员可以创建可重复使用的结构可以使用不同类型的数据结构。衡量此技能有助于评估候选人对Rust中的通用编程概念的理解及其使用通用结构编写灵活有效的代码的能力。

  • 智能指针

    智能指针是Rust的数据结构中的数据结构。与常规指针相比,这提供了额外的功能和安全保证。应衡量此技能以评估候选人在管理内存,避免内存泄漏以及使用智能指针中使用高级内存管理功能的能力。

  • 参考计数

    RUST中的参考计数涉及管理通过参考计数共享数据的所有权和寿命。评估这项技能有助于确定候选人对Rust的内存管理的理解,并通过参考计数来处理共享资源所有权的能力。

  • 线程池和工作池和工作者

    线程池和工人对生锈的并发和并行性。衡量此技能对于评估候选人对Rust的并发机制的了解,其利用线程池以进行有效执行的能力以及他们对创建工人线程进行分配工作负载的理解。

  • 所有权概念</h4> << P>所有权是Rust的一个基本概念,它决定了如何分配,访问和清理内存。评估这项技能有助于评估候选人对Rust中独特所有权,借用和终生的理解,从而使他们能够编写安全有效的代码。</p> <h4>循环和字符串和字符串

    循环和字符串是基本的几乎每种编程语言中使用的结构也不例外。衡量此技能使招聘人员能够评估候选人对循环结构的熟悉程度及其在Rust中操纵和处理字符串数据的能力。

  • oops概念

    oops(面向对象的编程系统)概念在包括Rust在内的许多编程语言中相关。评估这项技能有助于招聘人员确定候选人对封装,遗传,多态性和其他OOP原则的理解,以及他们将这些概念应用于生锈开发中的能力。

  • 通用迭代器

    通用迭代器对于对数据集合进行各种操作,对于生锈至关重要。应衡量此技能以评估候选人在Rust中使用和操纵迭代器的熟练程度,这有助于书写简洁,表现力和高效的代码。

  • 并发

    并发是同时执行多个任务的程序。衡量此技能有助于确定候选人对Rust的并发机制的理解,例如线程,通道和锁,以及它们编写既正确又有效的并发代码的能力。

生锈在线测试 常见问题解答

我可以将多个技能结合在一起,为一个自定义评估吗?

是的,一点没错。自定义评估是根据您的职位描述进行的,并将包括有关您指定的所有必备技能的问题。

您是否有任何反交换或策略功能?

我们具有以下反交易功能:

  • 不可解决的问题
  • IP策略
  • Web Protoring
  • 网络摄像头Proctoring
  • 窃检测
  • 安全浏览器

阅读有关[Proctoring功能](https://www.adaface.com/proctoring)的更多信息。

如何解释考试成绩?

要记住的主要问题是评估是消除工具,而不是选择工具。优化了技能评估,以帮助您消除在技术上没有资格担任该角色的候选人,它没有进行优化以帮助您找到该角色的最佳候选人。因此,使用评估的理想方法是确定阈值分数(通常为55%,我们为您提供基准测试),并邀请所有在下一轮面试中得分高于门槛的候选人。

我可以使用该测试的经验水平?

每个ADAFACE评估都是为您的职位描述/理想候选角色定制的(我们的主题专家将从我们的10000多个问题的图书馆中选择正确的问题)。可以为任何经验级别定制此评估。

每个候选人都会得到同样的问题吗?

是的,这使您比较候选人变得容易得多。 MCQ问题的选项和问题顺序是随机的。我们有[抗欺骗/策略](https://www.adaface.com/proctoring)功能。在我们的企业计划中,我们还可以选择使用类似难度级别的问题创建多个版本的相同评估。

我是候选人。我可以尝试练习测试吗?

不,不幸的是,我们目前不支持实践测试。但是,您可以使用我们的[示例问题](https://www.adaface.com/questions)进行练习。

使用此测试的成本是多少?

您可以查看我们的[定价计划](https://www.adaface.com/pricing/)。
