9 reasons why

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

Reason #1

Tests for on-the-job skills

The COBOL 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:

了解COBOL的基本概念和语法
证明在COBOL中宣布和操纵数据的熟练程度
使用COBOL程序部实施逻辑和流控制
在COBOL中使用文件并执行文件操作
在COBOL中分类和合并数据
在COBOL程序中有效使用条件语句
在COBOL中实现子程序和功能
处理COBOL中的错误和例外
编写高效，优化的COBOL代码
了解COBOL计划的结构和行为

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 COBOL在线测试将是不可行的.

🧐 Question
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 COBOL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.
