About the test:

The C++ Online Test uses scenario-based and code tracing MCQ questions to evaluate a candidate's ability to write C++ programs (data types, functions, data structures, STL), structure the code using Object-oriented programming principles (classes, inheritance, polymorphism, overloading), handle exceptions and manage memory. The test uses coding questions to evaluate hands-on C++ coding skills.

Covered skills:

  • C++ basics (Data Types; Variables; Operators)
  • modules and data structures
  • Functions
  • Pointers and references

Adaface C ++在线测试 is the most accurate way to shortlist C++ Developers



Reason #1

Tests for on-the-job skills

C ++在线测试可帮助招聘人员和招聘经理从简历中确定合格的候选人,并有助于做出客观的招聘决策。它减少了采访太多候选人的管理开销,并通过滤除了不合格的候选人来节省昂贵的工程时间。

测试筛选以下技能的候选者:

-C ++基本原理(变量,分支和循环,功能,参考参数,阵列,字符串,向量)

  • I/O在文件和I/O流上操作
  • 内存管理,包括指针,参考,移动和复制构造函数
  • OOPS概念(类,操作员超载,组成,继承,多态性,模板,并发等)
  • 实施常见数据结构和算法
  • 有效使用内置功能和指针
  • 标准模板库类(向量,集合,队列)
  • 图书馆公用事业 - 元组,对,日期和时间
  • 例外处理
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.

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.

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 C++ Online Test 将是不可行的.

Registration Queue
Logic
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

Longest Road

Solve
A startup company E-Motors is building driverless automated cars. The car contains a sensor that checks the road quality for the next N meters to decide the optimal speed at which the cars should move. We are given recorded data by the sensor in the form of an array, where each element of the array is the rating given to 1 meter of the road in sequence. 

The rating given by the sensor is from 1 to 100, where 100 represents the road with the best condition, and any rating above 60 is optimal. Find the longest stretch of road in meters that is categorized as optimal by the sensor.

The input is an array of "strings" which needs to be converted from string to integer/number inside the function.

Medium

Visitors Count
Strings
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 C++ Online Test 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the C++ Online Test 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.

Reason #7

Detailed scorecards & comparative results

Reason #8

High completion rate

Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

This is why Adaface has the highest test-completion rate (86%), which is more than 2x better than traditional assessments.

Reason #9

Advanced Proctoring


高级C ++开发人员的测试有何不同?

我们的主题专家以两种方式根据资历自定义测试:

  • 为高级开发人员选择的主题将是更高级别的,而对于初级开发人员来说,主题将围绕核心基础知识。这将确保对高级开发人员进行预期的在职技能的测试
  • 难度级别的问题将根据资历水平而变化。这样,高级开发人员会深入审查核心主题,而初级开发人员则根据核心主题进行审查

以下是高级开发人员评估中评估的一些主题:

-C ++并发(线程,Mutex,Package_task,Future,Async,Promise)

  • 基于锁定的数据结构的线程安全实现
  • 高级STL(优先队列,多地图,多组等)
  • 创建自己的功能模板和类模板
  • 非STL算法
  • 内存管理,包括指针,参考,移动和复制构造函数
  • 避免记忆泄漏并使用独特的指针,共享指针和虚弱的指针使用RAII策略
  • 界面分离和依赖性反转的知识
  • 功能编程和控制倒置

C++ Online Test FAQs

我可以在同一测试中评估C ++和嵌入式C吗?

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/)。

我可以免费试用吗?
