As of April 15, 2026, the Talend/Qlik academy page lists the Data Integration Certified Developer exam as 55 questions, 90 minutes, and a 70% passing score. Because Talend is now delivered through the Qlik Learning platform, the public fee is not published on the exam page — candidates should confirm pricing through Qlik Learning before scheduling. The exam targets Talend Studio 8.x skills including Jobs, Joblets, components, tMap, contexts, metadata, routines, triggers, debugging, and project management.

1In Talend Studio, what is the primary purpose of a project?

A.To store a single Job's JAR artifact only

B.A top-level container that groups related Jobs, metadata, routines, and other items

C.A running JobServer instance

D.A Git branch within TAC

Explanation: A Talend project is the top-level workspace that holds all related Jobs, contexts, metadata, routines, business models, and other repository items. Developers open a project in Studio to work with its contents.

2What is a reference project in Talend Studio?

A.A read-only project whose shared items are reused by another project

B.A Job used as a template for new Jobs

C.A backup copy stored on the JobServer

D.A project that can only be opened from TAC

Explanation: A reference project is declared as a dependency of another project and makes its shared items (routines, contexts, metadata, Joblets) available for reuse. Items remain read-only when accessed from the referencing project.

3Where does Talend Studio store local project workspace files by default when not connected to a remote repository?

A.In the TAC database

B.In the local Studio workspace directory on disk

C.In etcd

D.In a Nexus artifact repository

Explanation: When using a local connection, Studio writes project items to the workspace directory on the developer's disk. This is independent of TAC, Nexus, or any remote Git server.

4Which Studio perspective do you use to build and edit Data Integration Jobs?

A.Profiling

B.Mediation

C.Integration

D.MDM

Explanation: The Integration perspective is the default Data Integration workspace where you design Jobs, manage the repository, and work with components. Other perspectives target different Talend products.

5What is the primary benefit of using the repository over hard-coding values in individual Jobs?

A.It removes the need to compile Jobs

B.It enables reuse and centralized updates of metadata, contexts, and schemas

C.It automatically parallelizes Jobs

D.It prevents the Job from being deployed to TAC

Explanation: Repository items centralize things like database connections, file schemas, and contexts so multiple Jobs can share them. Updating the repository definition propagates to every Job that references it.

6In Talend Studio, what is a Joblet?

A.A reusable sub-flow of components that can be embedded in Jobs

B.A standalone JAR published to Nexus

C.A TAC scheduling definition

D.A type of context variable

Explanation: A Joblet packages a reusable group of components with its own input/output triggers. When placed inside a Job, it behaves like a single component and promotes reuse across Jobs.

7How do Joblets differ from child Jobs called with tRunJob?

A.Joblets run in a separate JVM; child Jobs share the JVM

B.Joblets are compiled in-line with the parent Job; child Jobs run as their own Job

C.Joblets cannot accept input rows

D.Joblets can only be used in Big Data Jobs

Explanation: A Joblet is inlined into the compiled parent Job, so it becomes part of the same compiled artifact and shares runtime state. A tRunJob call launches a separate Job that can have its own JVM context and lifecycle.

8Which Studio view shows component-specific properties such as filenames, schemas, and tMap expressions?

A.Problems view

B.Outline view

C.Component view

D.Navigator view

Explanation: The Component view (often called the Component tab) displays the configuration of whichever component is selected on the Job design canvas. Filenames, schemas, and tMap editors open from this tab.

9What does the 'Generated code' tab under a Job display?

A.The raw Java code that Talend will compile and execute for the Job

B.A visual preview of the Job diagram

C.The compiled JAR bytes

D.The contents of the TAC log table

Explanation: Talend Studio generates Java source code from the graphical Job. The Generated code tab lets developers inspect this Java, which is useful when debugging unusual runtime behavior.

10When you open a Job that references a repository schema, what happens if the schema was updated after the Job was last saved?

A.Studio silently ignores the change

B.Studio offers to propagate the change into the Job

C.The Job refuses to open

D.The repository schema is reverted to the Job's version

Explanation: When propagation is configured, Studio detects that a shared repository item changed and offers to apply the new definition to the Job. Developers can accept or refuse to keep flexibility.

About the Talend DI Developer Exam

The Talend Data Integration Certified Developer credential validates the ability to build, test, debug, and deploy Talend Studio Data Integration Jobs. It covers components such as tMap, tFilterRow, tDBInput/tDBOutput, and tRunJob, plus context variables, routines, metadata, version control, and Job orchestration in a standalone or collaborative project.

Talend DI Developer Study Tips from Top Performers

1Practice tMap thoroughly: inner join vs all matches, catch lookup inner join reject, and how join on expressions work.

2Learn the difference between context variables defined in a Job versus context groups pulled from the repository.

3Memorize the main triggers (OnSubjobOk, OnSubjobError, OnComponentOk, Run if) and when each fires.

4Understand how tRunJob passes context to child Jobs and when to use 'Transmit whole context' vs explicit mapping.

5Know how to use Joblets to reuse sub-flows and the tradeoffs versus standalone child Jobs.

6Get comfortable navigating the Metadata node: file delimited, database connection, generic schema, and how schemas propagate.

Frequently Asked Questions

How many questions are on the Talend Data Integration Developer exam?

The Talend Academy / Qlik Learning exam page lists 55 questions with a 90 minute time limit. Candidates need 70% to pass and receive the Talend Data Integration Certified Developer using Talend Studio badge on success.

What experience does Talend recommend before taking the exam?

Talend recommends at least six months of hands-on Talend Studio experience, comfort with data integration architecture concepts, and practice following best practices like using contexts, reference projects, and repository metadata. Completing the Data Integration Basics and Advanced learning plans is the standard preparation path.

How much does the Talend DI Developer exam cost?

Since Talend certification moved to the Qlik Learning platform, the public exam page does not publish a standalone price. You should check Qlik Learning before scheduling, because pricing can vary by region and by whether the exam is bundled with training.

What topics matter most on the exam?

Expect heavy emphasis on Talend Studio fundamentals, building Jobs with core components, tMap behavior, context variables, and Job orchestration with triggers and tRunJob. Metadata from the repository, Joblets, debugging, and basic version control are also in scope. Memorize tMap join models (inner join vs all matches, catch lookup inner join reject) and default trigger behavior.

Does the exam cover Talend Cloud or Talend Studio only?

The Data Integration Certified Developer exam is a Talend Studio exam; Talend Cloud Management Console topics are covered by the Talend Cloud Certified Administrator exam instead. You can still see Studio references to publish Jobs to remote engines, but you do not need to configure Cloud workspaces.

How long should I study for this exam?

If you already build Jobs at work, 3 to 5 weeks with 25 to 40 study hours is typical. New developers often need 6 to 8 weeks plus a sandbox project to practice tMap, metadata, contexts, and parent-child Jobs. Run timed sets of 55 questions to get comfortable with the 90 minute pace.
