Adaface PHP Test is the most accurate way to shortlist Core PHP Developers



Reason #1

Tests for on-the-job skills

The PHP 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:

  • Efficiently handling exceptions and errors
  • Understanding and implementing PHP OOPs concepts
  • Using and manipulating PHP built-in functions
  • Creating and utilizing PHP custom functions
  • Working with PHP Sessions for user management
  • Applying error and exception handling techniques in PHP
  • Performing database handling operations using PHP
  • Understanding PHP Fundamentals and syntax
Reason #2

No trick questions

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.

Why we started Adaface
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 PHP Online Test will be non-googleable.

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 PHP 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.

Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the PHP 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.

API or integrations: You can invite candidates directly from your ATS by using our pre-built integrations with popular ATS systems or building a custom integration with your in-house ATS.

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.
