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

These are just a small sample from our library of 15,000+ questions. The actual questions on this COBOL Online Test will be non-googleable.

🧐 Question
Medium Decision Control Arithmetic Operations Decision Structures Data Types	Solve
Consider the following COBOL program: What will the program display when it is executed?
Medium Multi Dimensional Arrays Arrays Data Processing Subroutines	Solve
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	Solve
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'.

Capability to handle error handling and exception management in COBOL

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 COBOL Online Test?

COBOL Data Division: COBOL Data Division is used to define data structures such as variables, records, and files. It is important to measure this skill to ensure that the candidate can effectively work with data and understand the different datatypes and data manipulation techniques in COBOL.

COBOL Procedure Division: COBOL Procedure Division is where the actual program logic is written. It includes statements such as perform, if-else, and do-while, among others. Measuring this skill helps evaluate the candidate's ability to write efficient and logical program logic using COBOL.

File Handling: File handling in COBOL involves reading, writing, and manipulating files. It is crucial to assess this skill as it determines if the candidate can work with external data sources and perform operations like record-level processing and file organization in COBOL.

Sorting and Merging: Sorting and merging involve arranging data in a specific sequence and combining data from multiple sources respectively. Testing this skill ensures that the candidate can effectively use sorting algorithms and understand merging techniques to perform operations like matching records and maintaining data integrity in COBOL programs.

Conditional Statements: Conditional statements in COBOL allow the program to make decisions and perform different actions based on certain conditions. Measuring this skill helps assess the candidate's ability to write accurate and efficient conditional statements to control program flow and make logical decisions in COBOL.

Subprograms and Functions: Subprograms and functions in COBOL are reusable code segments that can be called from different parts of a program. Evaluating this skill is essential to determine if the candidate can effectively modularize code, improve code maintainability, and reuse logic in COBOL programs.

Error Handling: Error handling in COBOL involves handling and reporting errors or exceptions that occur during program execution. Measuring this skill helps determine if the candidate can identify and handle errors gracefully, ensuring that the program continues to run smoothly and provides appropriate error messages or recovery mechanisms in COBOL.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.

I'm a candidate. Can I try a practice test?

No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.
