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 PHP Online 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 Exception Handling Syntax	Solve
What does the following code output?
Easy PDO MySQL Database Connections Php Data Binding Pdo Usage	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 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.

What topics are covered in the PHP Online Test?

PHP Fundamentals: PHP Fundamentals refers to the basic concepts and principles of the PHP programming language. This includes understanding variables, data types, operators, control structures, and basic syntax. Assessing this skill is important as it forms the foundation on which all PHP programming is built.

PHP OOPs: PHP OOPs (Object-Oriented Programming) is a programming paradigm that utilizes objects, classes, and inheritance to organize and structure code. Assessing this skill is essential as it allows developers to create modular, reusable, and maintainable code, leading to more efficient software development.

PHP built-in functions: PHP built-in functions are pre-defined functions provided by PHP that perform specific tasks. Assessing this skill is important as it demonstrates a candidate's familiarity with the standard library functions and their ability to utilize them effectively in PHP development.

PHP custom functions: PHP custom functions are user-defined functions that allow developers to encapsulate reusable blocks of code for specific tasks. Assessing this skill is valuable as it measures a candidate's ability to create and utilize custom functions, enhancing code reusability, readability, and maintainability.

Using PHP Sessions: Using PHP Sessions refers to the ability to manage and maintain user-specific data across multiple page requests by utilizing PHP session handling mechanisms. Assessing this skill is crucial as it determines a candidate's capability to implement user authentication, maintain user state, and personalize user experiences in web applications.

Error and Exception Handling: Error and Exception Handling in PHP involves the ability to identify, catch, and handle errors and exceptions that occur during the execution of PHP code. Assessing this skill is important as it showcases a candidate's understanding of how to gracefully handle errors, prevent application crashes, and maintain data integrity.

Database Handling: Database Handling in PHP involves interacting with databases to perform operations like storing, retrieving, updating, and deleting data using PHP. Assessing this skill is essential as it demonstrates a candidate's proficiency in working with databases, manipulating data, and implementing data-driven functionalities in web applications.

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.

What is the cost of using this test?

You can check out our pricing plans.

Can I get a free trial?

Yes, you can sign up for free and preview this test.

I just moved to a paid plan. How can I request a custom assessment?
