🧐 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 -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.

Sikker browser

Læs mere om Proctoring Features.

Hvordan fortolker jeg testresultater?

Den primære ting at huske på er, at en vurdering er et elimineringsværktøj, ikke et udvælgelsesværktøj. En færdighedsvurdering er optimeret for at hjælpe dig med at eliminere kandidater, der ikke er teknisk kvalificerede til rollen, den er ikke optimeret til at hjælpe dig med at finde den bedste kandidat til rollen. Så den ideelle måde at bruge en vurdering på er at beslutte en tærskelværdi (typisk 55%, vi hjælper dig med benchmark) og inviterer alle kandidater, der scorer over tærsklen for de næste interviewrunder.

Hvilken oplevelsesniveau kan jeg bruge denne test til?

Hver Adaface -vurdering tilpasses til din jobbeskrivelse/ ideel kandidatperson (vores emneeksperter vælger de rigtige spørgsmål til din vurdering fra vores bibliotek på 10000+ spørgsmål). Denne vurdering kan tilpasses til ethvert erfaringsniveau.

Får hver kandidat de samme spørgsmål?

Ja, det gør det meget lettere for dig at sammenligne kandidater. Valgmuligheder for MCQ -spørgsmål og rækkefølgen af spørgsmål randomiseres. Vi har anti-cheating/proctoring funktioner på plads. I vores virksomhedsplan har vi også muligheden for at oprette flere versioner af den samme vurdering med spørgsmål om lignende vanskelighedsniveauer.
