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 & WordPress Online Test will be non-googleable.

🧐 Question

Medium

Custom WordPress Shortcode
Shortcodes
Solve
You're creating a custom WordPress shortcode that users can insert into their posts and pages to display a promotional banner. Your initial PHP code is as follows:
 image
A user inserts your shortcode into a post like this:
 image
However, when the user previews the post, the content inside the `[promo-banner]` shortcode isn't displayed. Instead, the user sees the shortcode itself.

What change can you make to fix this issue?
A: Replace `'promo-banner'` with `'[promo-banner]'` in the `add_shortcode` function.
B: Replace `'promo-banner'` with `'[promo-banner]'` in the shortcode inserted into the post.
C: Change the `promo_banner_shortcode` function to accept only one parameter.
D: Use `do_shortcode` function to process the `$content` inside the `promo_banner_shortcode` function.
E: Replace `$content` with `$atts['content']` in the `promo_banner_shortcode` function.

Medium

Iteration in WordPress Plugin
Asynchronous JavaScript
Solve
You're developing a WordPress plugin where you need to fetch comments for a list of posts from a WordPress database using AJAX. The JavaScript code is as follows:
 image
The processComments function processes the comments for other operations and is working as expected.

However, when running the code, you notice that the console logs for fetched comments don't appear in the order of the post IDs. Instead, the logs appear in a seemingly random order each time.

What change can you make to ensure the comments are fetched and processed in the order of the post IDs?
A: Use a traditional for loop instead of forEach.
B: Use setTimeout to delay the execution of fetchComments.
C: Use sort on postIDs before calling forEach.
D: Change forEach to map and use Promise.all.
E: Make processComments function asynchronous and await it in the forEach loop.

Medium

Responsive load
Optimization
Solve
Here’s the code snippet of interest from a client's WordPress code:
 image
 image
You are reviewing the client's code and have to make recommendations to improve speed of the WordPress site. Which of these are good recommendations?
A: Cache the website to improve the site but need to move the responsive logic to CSS. The conditional logic might not be cached if the cache provider does not trigger the conditionals

B: Cache the website to improve the site. No need to move the responsive logic to CSS

C: jQuery is very commonly loaded on live sites multiple times due to poorly written plugins/themes. Ensure required JS files are enqueued only once and when they are needed

D: CSS in <head> file will affect the speed of the site since the entire CSS file has to be loaded before rendering the site. It is advised to load only the CSS that is mandatory in the <head> and move the rest of the CSS to the later portions of the HTML

Medium

Shortcode Development in WordPress
Shortcodes
WP_Query
Loop
Solve
You're developing a WordPress plugin that provides a shortcode to display the latest posts. The shortcode is [latest-posts count="3"], where the "count" attribute determines the number of latest posts to display. 

Your initial PHP code is as follows:
 image
You test the shortcode on a page and find that the page content following the shortcode doesn't display.

What change can you make to fix this issue?
A: Use `return $query->have_posts();` instead of `$query->the_post();`.
B: Use `wp_reset_query();` after the while loop.
C: Use `the_content();` after the while loop.
D: Use `wp_reset_postdata();` after the while loop.
E: Use `return $output;` before the while loop.

Medium

WP REST API
REST API
HTTP Requests
JSON Response
Solve
You're developing a custom WordPress plugin to fetch and display a list of posts using the WordPress REST API. Your initial JavaScript code is as follows:
 image
This code works fine when the website URL is `http://localhost/wordpress`. However, when you move your website to a different domain (for example, `http://example.com`), the list of posts doesn't display.

What change can you make to fix this issue?
A: Replace `/wp-json/wp/v2/posts` with `http://example.com/wp-json/wp/v2/posts`.
B: Replace `/wp-json/wp/v2/posts` with `http://localhost/wordpress/wp-json/wp/v2/posts`.
C: Use `wp_localize_script` to pass the website URL from PHP to JavaScript, and prepend it to `/wp-json/wp/v2/posts`.
D: Use `admin_url('admin-ajax.php')` to replace `/wp-json/wp/v2/posts`.
E: Use `site_url('/wp-json/wp/v2/posts')` to replace `/wp-json/wp/v2/posts`.

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 & WordPress 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 & WordPress 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.

invite candidates
Reason #7

Detailed scorecards & benchmarks

Reason #8

High completion rate

Adaface tests are conversational, low-stress, and take just 25-40 mins to complete.

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

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.
