Adaface PHP, Laravel and SQL Online Test is the most accurate way to shortlist PHP Developers



Reason #1

Tests for on-the-job skills

The PHP, Laravel and SQL 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.

Non-googleable questions & proctoring features enable you to be comfortable with conducting assessments online. The PHP, Laravel and SQL Online Test is ideal for helping recruiters identify which candidates have the skills to do well on the job.

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.

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.

These are just a small sample from our library of 10,000+ questions. The actual questions on this PHP, Laravel & SQL Test will be non-googleable.

Solve
You are developing a Laravel application that has a PostController for managing blog posts. The routes for this controller are set up as a resource route in your web.php file:
 image
You have already created a middleware called EnsureAdminRole to restrict access to certain routes for admin users. Now, you want to apply this middleware to the create, edit, update, and delete routes for the PostController, but not the index or show routes.

Which of the following ways would correctly apply the EnsureAdminRole middleware to these routes?
 image

Medium

Custom Validation Rule
Validation
Request Handling
Custom Rules
Solve
In your Laravel application, you are implementing a registration form where users enter their birthdate as a string in the 'Y-m-d' format. You want to ensure that only users aged 18 years or older can register. To achieve this, you decide to write a custom validation rule. Consider the following implementation of the custom rule and a function to handle the registration request:
 image
Which of the following code snippets correctly fills the passes method in the AgeRestriction class to ensure that only users aged 18 or older can register, given that the birthdate is a string in the 'Y-m-d' format?
 image

Eloquent Relationship Handling
ORM
Relationships
Database Operations
Solve
Consider the following code snippet in a Laravel application:
 image
Assume the user 'John Doe' is the first user in the User table. You want to retrieve all comments belonging to a post made by this user ('John Doe'). Which of the following Eloquent expressions is the correct way to achieve this?
 image

Medium

Route Model Binding
Routing
Controllers
Eloquent
Solve
In your Laravel application, you're making use of route model binding to handle retrieving models based on the incoming request. You have a route defined as follows:
 image
In your PostController, the show method looks like this:
 image
Now, imagine that instead of using the ID, you want to retrieve posts by their 'slug' for SEO purposes. Which of the following changes should you make in order to achieve this?
A: Modify the route to Route::get('/posts/{slug}', 'PostController@show'); and change the show method to public function show($slug).
B: Modify the getRouteKeyName method in the Post model to return 'slug'.
C: Change the show method to public function show(Post $slug).
D: No changes are needed, Laravel will automatically use the 'slug' if it exists.

Medium

Service Container
Service Container
Dependency Injection
Solve
In a Laravel application, the Service Container is a powerful tool for managing class dependencies and performing dependency injection. You're building a payment feature and created an interface PaymentGatewayInterface and two concrete classes, StripePaymentGateway and PaypalPaymentGateway, which implement this interface.

The application should use StripePaymentGateway for users located in the US, and PaypalPaymentGateway for users located in Europe.

Which of the following approach would you use to register these bindings in the Service Container?
A: Use App::bind(PaymentGatewayInterface::class, StripePaymentGateway::class) for US users and App::bind(PaymentGatewayInterface::class, PaypalPaymentGateway::class) for European users.

B: Use App::singleton(PaymentGatewayInterface::class, StripePaymentGateway::class) for US users and App::singleton(PaymentGatewayInterface::class, PaypalPaymentGateway::class) for European users.

C: Use a conditional statement within the binding closure of App::bind to check the user's location and bind the appropriate concrete class.

D: Use App::instance(PaymentGatewayInterface::class, new StripePaymentGateway) for US users and App::instance(PaymentGatewayInterface::class, new PaypalPaymentGateway) for European users.

E: Use App::when('App\\Http\\Controllers\\PaymentController')->needs(PaymentGatewayInterface::class)->give(StripePaymentGateway::class) for US users and the same method with PaypalPaymentGateway::class for European users.

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.

With Adaface, we were able to optimise our initial screening process by upwards of 75%, freeing up precious time for both hiring managers and our talent acquisition team alike!


Brandon Lee, Head of People, Love, Bonito

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment PHP, Laravel & SQL 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, Laravel & SQL 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.

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.

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
  • Web proctoring
  • Webcam proctoring
  • Plagiarism detection
  • Secure browser

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?
