9 reasons why

Adaface JCL Test is the most accurate way to shortlist 大型机开发人员s

Reason #1

Tests for on-the-job skills

The JCL 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:

能够写和理解JCL命令的能力
有效使用JCL语句的能力
精通JCL公用事业
理解和使用JCL参数
控制JCL作业执行的能力
了解工作计划和依赖性
在JCL中对工作执行的强烈了解

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 JCL测试将是不可行的.

🧐 Question
Medium Disposition Parameters JCL Syntax Dataset Management	Try practice test
Consider the following JCL snippet: In MYJOB, PROG1 in STEP1 uses the dataset MY.DS.INPUT with a disposition of (OLD,DELETE,KEEP). PROG2 in STEP2 also uses the dataset MY.DS.INPUT with a disposition of (NEW,PASS,DELETE). Assume that STEP1 executed successfully, but STEP2 failed during its execution. What would be the status of the dataset MY.DS.INPUT after the job MYJOB is run? A: MY.DS.INPUT will be deleted. B: MY.DS.INPUT will be kept and can be used by other jobs. C: MY.DS.INPUT will be newly created. D: MY.DS.INPUT will be available for the duration of the job, then deleted. E: MY.DS.INPUT status cannot be determined with the provided information.
Medium Execution Order and Return Codes Job Control Execution Order Return Codes	Try practice test
Consider a JCL job that needs to execute five steps: STEP01, STEP02, STEP03, STEP04, and STEP05. The steps represent data initialization, data processing, data validation, error handling, and job finalization respectively. The execution rules are as follows: 1. The job should always start with STEP01. 2. STEP02 should only execute if STEP01 completes successfully with a return code (RC) of 0. 3. STEP03 should always run after STEP02, irrespective of STEP02's return code. 4. STEP04 should only execute if either STEP02 or STEP03 fails, i.e., return a code not equal to 0. 5. STEP05 should always be the last step, and should only execute if all the previous steps were successful (each returning a code of 0). Given these rules, how would you design the JCL job using the IF/THEN/ELSE/ENDIF construct?
Medium Decision Control Arithmetic Operations Decision Structures Data Types	Try practice test
Consider the following COBOL program: What will the program display when it is executed?
Medium Multi Dimensional Arrays Arrays Data Processing Subroutines	Try practice test
Consider the following pseudocode snippet in COBOL: After executing this program, what will be the final state of StrArr?
Medium VSAM File Processing in COBOL VSAM File Handling	Try practice test
Consider the following COBOL code snippet. The program aims to read from a VSAM Key-Sequenced Data Set (KSDS) named 'CUSTOMER-FILE' which contains customer records. The program reads the file in ascending order by 'CUSTOMER-ID', performs some processing (not shown here), and then displays the 'CUSTOMER-NAME' of the last record read. Assuming there are no syntax errors and the 'CUSTOMER-FILE' is present and accessible, what will the program display as the last customer's name after executing this COBOL program? A: The program will display the name of the customer with the highest 'CUSTOMER-ID'. B: The program will display the name of the customer with the lowest 'CUSTOMER-ID'. C: The program will not display any customer name. D: The program will display the name of the first customer in the 'CUSTOMER-FILE'. E: The program will display an uninitialized or random 'LAST-NAME'.

Reason #5

Designed for elimination, not selection

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

What topics are covered in the JCL Online Test?

JCL语句
JCL语句是JCL中编写的说明（作业控制语言）指定执行作业所需的步骤和参数。这些语句定义了作业，作业步骤，输入/输出文件以及其他必要的详细信息。测量测试中的这一技能有助于确定候选人对JCL语句语法的熟悉程度及其创建无错误和高效的工作控制程序的能力。
JCL UTITIORITION
JCL实用程序是预定义的程序该在大型机环境中执行特定的任务，例如复制，分类，合并和操纵数据集。评估候选人在测试中对JCL公用事业的知识评估其有效利用这些工具的能力，以实现数据管理和处理任务，从而有助于工作执行的整体效率。
JCL参数
JCL参数是在作业控制语言中提供的值，它影响了作业的行为和执行。这些参数定义了与工作相关的属性，例如数据集名称，程序选项，系统设置和资源分配。评估候选人对测试中JCL参数的理解有助于衡量其定义和控制工作特征的能力，确保成功执行工作。
JCL工作控制
JCL JCL作业控制是指该技能在大型机环境中有效管理职位执行。它涉及组织工作步骤，定义依赖项，指定执行顺序以及监视资源以确保最佳绩效。测量测试中的此技能有助于确定可以有效处理工作控制任务的候选人，确保及时且无错误执行关键工作工作流程。
作业计划
作业计划需要创建一个安排计算系统中执行各种作业的时间。调度涉及确定工作的适当时间和测序，以优化系统资源并满足组织要求。评估候选人在此测试中的职位计划熟练程度，使招聘人员能够确定可以有效管理工作时间表的个人，确保业务流程的平稳运作。
工作依赖性
工作依赖性是指工作完成的工作之间的关系取决于成功执行另一个工作。理解和管理工作依赖性对于维持适当的工作执行顺序，避免冲突以及确保工作流程的准确，有效地进行工作流程至关重要。评估候选人在测试中对工作依赖性的知识有助于确定他们有效地管理相互依存工作的能力，最大程度地减少错误和延迟。
工作执行
作业执行是指运行作业的过程或按照定义的说明和计划在计算系统中的任务。此技能包括管理资源，确保在指定的时间范围内完成工作完成，监视工作状态以及解决执行过程中可能发生的任何问题或错误。在此测试中衡量候选人在工作执行中的能力有助于评估他们有效执行与工作相关的任务的能力，确保工作流程平稳并实现组织目标。
