9 reasons why

Adaface Symfony Test is the most accurate way to shortlist Symfony Developers

Reason #1

Tests for on-the-job skills

The Symfony Online Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

Able to efficiently handle exceptions and errors
Proficient in Symfony fundamentals
Strong understanding of PHP programming
Knowledge of events and event listeners in Symfony
Experience in working with forms in Symfony
Skilled in web development using Symfony
Solid foundation in object-oriented programming
Ability to integrate databases in Symfony applications

Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Reason #3

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 10,000+ questions. The actual questions on this Symfony Test will be non-googleable.

🧐 Question
Medium Dynamic Function Calls Arrays Strings Functions	Solve
Consider the following PHP pseudo code: The processArray function processes the $data array based on the transformation operations defined in the $operations array. The operations array dictates which transformation function to call for each sub-array key. What will be the output of the above code?
Hard Alter and Change OOPs	Solve
What does the following code output?
Hard Exceptions Exceptions	Solve
What does the following code output?
Easy PDO MySQL Database Connections	Solve
Consider the following table data and PHP code. What is the result?
Medium Session Management and Object Serialization Sessions Serialization	Solve
Consider the following PHP script: Assuming you run the script twice in a row without clearing the session data, what will be the output on the second run?
Easy Registration Queue Logic Queues	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	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.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Symfony 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.

About the Symfony Assessment Test

Why you should use Pre-employment Symfony Online Test?

The Symfony 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 of Symfony Fundamentals
Proficiency in PHP Programming
Knowledge of Events and Event Listeners in Symfony
Experience with Forms in Symfony
Ability to develop Web Applications in Symfony
Strong grasp of Object-Oriented Programming principles
Familiarity with Database Integration in Symfony
Proficient in handling exceptions and errors in Symfony
Experience with Symfony's routing and URL generation
Ability to optimize and improve Symfony application performance

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 Symfony Online Test?

Symfony Fundamentals
Symfony Fundamentals covers the basic concepts and principles of the Symfony framework, such as routing, controllers, services, and application structure. This skill is crucial to measure in the test as it forms the foundation for developing robust and scalable Symfony applications.
PHP Programming
PHP Programming involves writing code in the PHP language to develop dynamic web applications. This skill is essential to assess to ensure candidates have a strong understanding of PHP syntax, data structures, functions, and object-oriented programming concepts, which are heavily used in Symfony development.
Events and Event Listeners
Events and Event Listeners are an integral part of the Symfony framework, allowing developers to implement robust event-driven architectures. Assessing this skill helps recruiters evaluate candidates' ability to correctly implement and manage events and event listeners in Symfony applications, enabling efficient communication and decoupling of components.
Forms
Forms in Symfony provide a convenient way to handle HTML forms and validate user input. Measuring this skill ensures that candidates are proficient in creating and handling forms using Symfony's built-in form component, enabling recruiters to assess their ability to implement form validation and handle form rendering and submission.
Web Development
Web Development in the context of this test refers to candidates' ability to develop dynamic, scalable, and reliable web applications using Symfony. Assessing this skill allows recruiters to gauge candidates' proficiency in building web applications that follow best practices such as security, performance, and maintainability.
Object-Oriented Programming
Object-Oriented Programming is a fundamental concept in software development, and it plays a crucial role in Symfony application development. Measuring this skill helps recruiters assess candidates' understanding of OOP principles, such as encapsulation, inheritance, and polymorphism, and their ability to design and implement object-oriented solutions in Symfony projects.
Database Integration
Database Integration involves connecting Symfony applications to databases and performing CRUD operations. This skill is important to measure as it assesses candidates' ability to interact with databases using Symfony's database abstraction layer, allowing recruiters to evaluate their knowledge of SQL queries, data modeling, and database performance optimization.

Symfony Hiring Test FAQs

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

Non-googleable questions
IP proctoring
Screen proctoring
Web proctoring
Webcam proctoring
Plagiarism detection
Secure browser
Copy paste protection

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.
