🧐 Question

Medium

Conditional Processing
Row Filtering
Component Linking
Job Design
Try practice test
Consider a Talend job that reads rows from a tFileInputDelimited component and intends to process them through a series of transformations. Here's a pseudocode representation of a segment of your Talend job:
 image
You need to implement this logic within your Talend job such that rows with a "columnValue" greater than 100 follow one transformation path and others follow a different transformation path. Which of the following actions would help achieve this desired behavior?
A: Use a tFlowToIterate component after the tFileInputDelimited to iterate over rows and use a Java condition to route the data.
B: In the tMap component, set filters on the output links to achieve conditional routing based on "columnValue".
C: Place two tMap components side by side after tFileInputDelimited and use "columnValue" in each to filter rows.
D: Use a tSplitRow component after tFileInputDelimited to split rows based on the condition and connect to respective tMap components.
E: Implement a custom code component like tJavaRow to determine the flow of rows.

Medium

Dynamic Product API
Schema Evolution
Dynamic Data Types
API Integration
Try practice test
You're building a Talend job that integrates with an e-commerce platform's Product API. Over time, the platform has added, removed, or changed fields within the API response, making it a challenge to keep up with the schema changes. A typical API response might look like:
 image
However, fields like specs might have additional attributes in the future, or some fields might be deprecated.

The primary goal of your Talend job is:
 image
Given this scenario, how should you best handle the dynamic nature of the Product API schema in your Talend job?
A: Use tExtractJSONFields and adjust the XPath query every time the API changes.
B: Set a fixed schema in tMap based on the most common fields and ignore new additions.
C: Define the input schema of tMap as "Dynamic", and map necessary fields to a stable output schema.
D: Set the tOutputDB schema to "Dynamic" and let the database adjust to incoming changes.
E: Process the raw JSON strings directly in tMap and use string manipulations for transformations.

Medium

Multi-source Data Aggregation
Data Transformation
Joins
Lookup
Aggregation
Data Filters
Try practice test
You're working with three different data sources in a Talend job: a MySQL table (users), an Oracle table (transactions), and a CSV file (rewards). The goal is to create a report containing the user's name, total transaction amount, and reward points, but only for users who have both made a transaction and earned rewards. Here are the key columns from each source:

- users: user_id, user_name
- transactions: trans_id, user_id, amount
- rewards: reward_id, user_id, points

Which of the following sequences best accomplishes this?
A: Use tMySQLInput, tOracleInput, and tFileInputDelimited in parallel -> tDenormalize to combine all results. Filter and aggregate results using tMap and then pass to tOutput.
B: Use tMySQLInput and tOracleInput in parallel -> tJoin to combine results on user_id. Use tFilterRow to filter transactions and then join the filtered result with tFileInputDelimited using tMap.
C: Use tMySQLInput -> tMap to join with tOracleInput based on user_id. Use another tMap to join the result with tFileInputDelimited. Aggregate results using tAggregateRow based on user_name, and filter using tFilterRow.
D: Use tMySQLInput -> tMap to join with tOracleInput based on user_id. Then, join the result with tFileInputDelimited on user_id. Apply filters in tMap to exclude rows where users neither made a transaction nor earned rewards.
E: Use tMySQLInput -> tMap to lookup and join with tFileInputDelimited based on user_id. Then, join this result with tOracleInput using another tMap. Apply filters in the final tMap to only include the desired rows.

Medium

Null Dates in tJavaRow
Java Programming
Null Safety
Date Manipulation
Exception Handling
Try practice test
You're designing a Talend job to process e-commerce transactions. Each record has an "interactionType" field and a lastPurchase date field. For records with "SALE" as the interaction type, you want to calculate the number of days since the lastPurchase. However, the lastPurchase field can be null due to certain circumstances.

Here's the Java code within the tJavaRow component:
 image
Which of the following statements is TRUE regarding the code?
A: If the lastPurchase field is null, the code will throw a runtime exception.
B: The daysSinceLastPurchase field is set to -1 solely in case of a date parsing error.
C: All records with "SALE" as the interaction type will invariably have a non-negative daysSinceLastPurchase value.
D: The code inherently assumes that every transaction of type "SALE" contains a valid lastPurchase date.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Talend Online 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.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the Talend Online Test from your dashboard by entering their email address.

Public link: You can create a public link for each test that you can share with candidates.

Read more about the proctoring features.

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.
