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 Dart Online Test will be non-googleable.

🧐 Question
Medium Async Await Asynchronous Programming Asynchronous Programming With Dart	Solve
Review the following Dart code: The code reads data from a file synchronously. The code blocks while waiting for file I/O. Which of the following is the proper asynchronous version of the same code? - Assume readAsString is asynchronous version of readAsStringSync - Lines with changes compared to original code are marked with // #
Easy Iterable Sync Asynchronous Programming	Solve
What would the following Dart code print?
Medium Method Overriding Constructors Inheritance Method Overriding	Solve
Consider the following Dart code: What will be the output of the above Dart code?
Easy Registration Queue Logic Queues Sorting By Custom Order	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic String Parsing Character Counting	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Why you should use Pre-employment Dart Test?

The Dart Online Test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

Understanding Dart Basics and syntax
Working with Variables and Data Types in Dart
Implementing Control Flow in Dart
Utilizing Functions in Dart
Applying Object-Oriented Programming concepts in Dart
Working with Collections in Dart
Handling Errors and Exceptions in Dart
Implementing Asynchronous Programming in Dart
Testing and Debugging Dart code
Integrating Dart with other technologies

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 Dart Test?

Dart Basics: Dart Basics refers to the fundamental concepts and syntax of the Dart programming language, such as variables, expressions, and control flow. Understanding Dart Basics is crucial for developers to write clean and efficient code in Dart.

Variables and Data Types: Variables and Data Types encompass the different types of data that can be stored in variables and manipulated in Dart. This skill measures a candidate's ability to correctly declare and use variables, as well as their knowledge of data types and type conversions.

Control Flow: Control Flow involves the flow of execution in a program, including conditionals (if, else if, else), loops (for, while), and switch statements. This skill assesses a candidate's understanding of how to control the flow of their Dart code based on different conditions and iteratively execute certain blocks of code.

Functions: Functions in Dart are reusable blocks of code that perform specific tasks. This skill evaluates a candidate's familiarity with creating and using functions, including defining function parameters, returning values, and understanding the scope of variables within functions.

Object-Oriented Programming: Object-Oriented Programming (OOP) is a programming paradigm that uses objects to model real-world concepts. This skill measures a candidate's knowledge of OOP concepts in Dart, such as classes, objects, inheritance, and encapsulation, which are essential for building modular and maintainable code.

Collections: Collections refer to data structures that store multiple elements in a single variable. This skill assesses a candidate's understanding of different collections in Dart, including lists, sets, and maps, and their ability to perform operations like iterating, accessing, adding, and removing elements from these collections.

Error Handling: Error Handling involves catching and handling errors and exceptions that can occur during the execution of a Dart program. This skill measures a candidate's proficiency in using try-catch blocks, throwing and handling custom exceptions, and understanding the concept of stack traces to improve error diagnostics and debugging.

Asynchronous Programming: Asynchronous Programming in Dart enables concurrent execution, allowing tasks to execute independently and not block the main thread. This skill evaluates a candidate's familiarity with asynchronous programming concepts, such as using async and await keywords, Futures, Streams, and handling asynchronous errors, which are essential for efficient and responsive Dart applications.

Testing and Debugging: Testing and Debugging skills assess a candidate's ability to identify and fix issues in Dart code. This includes writing and executing unit tests, using debugging tools to pinpoint errors, and employing best practices to ensure code quality and correctness.
