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.

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.

About the PHP, Laravel and SQL Assessment Test

Why you should use Pre-employment PHP, Laravel and SQL Online Test?

The PHP, Laravel & SQL 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 and applying PHP syntax basics
  • Working with PHP data structures like arrays and objects
  • Implementing PHP object-oriented programming concepts
  • Performing CRUD operations in SQL
  • Working with SQL joins and indexes
  • Creating and using Laravel templates and components
  • Defining routes and controllers in Laravel
  • Managing database migrations and relationships
  • Demonstrating proficiency in PHP programming
  • Troubleshooting and debugging PHP, Laravel, and SQL code

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 PHP, Laravel and SQL Online Test?

  • PHP Syntax Basics

    PHP Syntax Basics refers to the fundamental rules and conventions of writing PHP code, including its syntax, variables, data types, operators, and control structures. It is important to measure this skill in the test to ensure that candidates have a strong foundation in PHP programming, which is necessary for successfully working with PHP frameworks like Laravel and performing database operations using SQL queries.

  • PHP Data Structures

    PHP Data Structures involve the organization and storage of data in PHP, such as arrays, strings, objects, and maps. Assessing this skill allows recruiters to evaluate a candidate's ability to manipulate and manage data effectively, which is crucial for developing complex web applications and working with databases in PHP.

  • PHP OOPs

    PHP OOPs, or PHP Object-Oriented Programming, is a programming paradigm that focuses on the creation and interaction of objects. This skill is essential for developing modular, reusable, and scalable code using concepts such as classes, objects, inheritance, encapsulation, and polymorphism. By measuring this skill, recruiters can assess a candidate's proficiency in writing object-oriented code, a fundamental aspect of PHP and Laravel development.

  • SQL CRUD Operations

    SQL CRUD Operations refer to the Create, Read, Update, and Delete operations performed on a database using SQL queries. This skill is essential for developers working with databases in PHP and Laravel, as it allows them to interact with and manipulate data stored in the database. Assessing this skill helps recruiters determine a candidate's ability to perform basic database operations efficiently and accurately.

  • SQL Joins and Indexes

    SQL Joins and Indexes are crucial components of database management and optimization. SQL Joins enable developers to combine data from multiple tables based on common columns, while SQL Indexes enhance query performance by providing faster data access. Measuring this skill ensures that candidates can effectively retrieve and manipulate data from a relational database, improving the overall efficiency and performance of their PHP and Laravel applications.

  • Laravel Templates and Components

    Laravel Templates and Components are essential for designing and building user interfaces in Laravel applications. Templates provide a consistent layout for web pages, while Components encapsulate reusable UI elements. Assessing this skill allows recruiters to evaluate a candidate's ability to create visually appealing and interactive interfaces using Laravel's powerful templating system.

  • Laravel routes and controllers

    Laravel routes and controllers form the backbone of the application's logic and request handling. Routes define the URL structure and map it to corresponding controller methods, which handle the incoming requests. Evaluating this skill helps recruiters gauge a candidate's understanding of routing and controller implementation in Laravel, ensuring they can effectively handle and process user requests.

  • Database migrations and relationships

    Database migrations in Laravel are used to manage changes to the database schema and structure over time. They allow developers to version control and easily deploy these changes across different environments. Assessing this skill ensures that candidates can confidently design and implement database migrations, as well as establish relationships between different database tables, ensuring efficient data organization and retrieval in Laravel applications.

  • PHP Programming

    PHP Programming refers to the overall proficiency in the PHP programming language, encompassing all the skills mentioned above, along with knowledge of best practices, error handling, debugging, and performance optimization. Evaluating this skill provides recruiters with a comprehensive assessment of a candidate's ability to develop scalable and maintainable PHP applications using Laravel and SQL.

PHP, Laravel and SQL 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.

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.
