PHP, Drupal & SQL Online Test

The PHP, Drupal & SQL Test uses scenario-based MCQs to evaluate candidates on their proficiency in PHP programming language, Drupal content management system, and SQL database. The test assesses candidates' understanding of topics such as module development, theming, database interactions, Drupal architecture, SQL queries, and database design principles. Candidates are evaluated on their ability to use these technologies to develop custom modules, themes, and configurations for Drupal, as well as their proficiency in writing efficient and effective SQL queries for data manipulation and retrieval.

Screen candidates with the highest quality 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, Drupal & SQL 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?
Medium Access content Routes Controllers	Solve
Review the following Drupal code: Pick the correct statements: A: When /sample is accessed, access is allowed without checking for permissions and SampleController::content method is invoked B: When /sample is accessed, ‘access content’ permission is checked on the accessing user and, if access is granted, SampleController::content method is invoked C: When /sample is accessed, the page outputs ‘A’ on the page with title ‘B’ D: When /sample is accessed, the page outputs ‘B’ on the page with title ‘A’ E: When /sample is accessed, the page outputs ‘A’ on the page with no title F: When /sample is accessed, the page outputs nothing on the page with title ‘B’
Medium Insert Queries Database API	Solve
Review the following Drupal code: Pick the correct statements: A: Both the snippets create the queries to run but are not executed until $query→execute() is called B: When Snippet 2 is run, the insert statements are executed one after the other always. Equivalent to calling →execute() two separate times for each item in $values. C: When Snippet 2 is run, depending on the database, the insert statements will be executed together in a transaction D: The return value of $result→execute will be the inserted record entry
Medium Multi Select JOIN GROUP BY	Solve
Consider the following SQL table: How many rows does the following SQL query return?
Medium nth highest sales Nested queries User Defined Functions	Solve
Consider the following SQL table: Which of the following SQL commands will find the ‘nth highest Sales’ if it exists (returns null otherwise)?
Medium Select & IN Nested queries	Solve
Consider the following SQL table: Which of the following SQL queries would return the year when neither a football or cricket winner was chosen?
Medium Sorting Ubers Nested queries Join Comparison operators	Solve
Consider the following SQL table: What will be the first two tuples resulting from the following SQL command?
Hard With, AVG & SUM MAX() MIN() Aggregate functions	Solve
Consider the following SQL table: How many tuples does the following query return?
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.
