Interested in hiring Frontend Developers with JavaScript expertise?

  • Suppose you are interested in hiring a good Frontend Developer with expertise in various JavaScript Frameworks like AngularJS, ReactJS, EmberJS, BackboneJS, jQuery or GWT. You post Job Descriptions on various online job portals and also partner with Candidate Sourcing Vendors. As a result, you end up with a pool of candidates interested in your job opening
  • What you have: 250 CVs from interested candidates.
  • What you don’t have: The time or the resources to conduct 250 interviews.
  • CV based filtering is extremely ad-hoc and often results in errors.
    • Candidates with in-depth knowledge on Mobile App Development can be ignored because their academics are not good or their CV is not well formatted
    • Candidates with good grades and neat CVs are often selected for interviews, even though they don’t have the relevant Software Technical Skills you are looking for.
  • Pouring over CVs from hundreds of candidates is also a painful, time-consuming activity

Our Recruitment Testing Philosophy

Our Recruitment Testing Philosophy is simple: “Align the recruitment tests for a role with the actual duties that a candidate must fulfill on a daily basis, if hired for that role.”

We believe that this alignment will help Recruiters maximize their Interview Hit Rate and reduce Cost per Hire

Logical Reasoning
Data Interpretation And Analytical Skills

Our Recommendation:

Ask all interested candidates to take the Frontend Developer Screening Test hosted by CodeGround Recruitment Testing Platform. [Link to Sample test]

  • You can ask MCQs on JavaScript or specific JS Frameworks
  • You can give programming questions along with test cases and ask candidates to write code to satisfy the test cases. Solutions to these programming questions should be coded using JavaScript.
  • You can share code with some bugs and ask candidates to debug it to address all corner cases
  • You can give a mini-project , asking the candidates to complete the project in a 2 day duration. (see illustration)

Illustration – Simple Form with AJAX verification

Please create a web application that uses HTML, JS and CSS for the UI and PHP in the backend. This application should have two pages.

The first page should be a form where users can fill in the information as per the fields shown below:

  • Name
  • Age
  • Email
  • Year Of Graduation

Proper validation should be performed on the form inputs as values are being typed in dynamically. If validation fails, the user must be informed immediately as he is typing in values.

  • Validation on Name: No special characters or numerals allowed
  • Validation on Age: This is a positive number less than 150
  • Validation on Email: Should be in accordance with a proper email format. This email should also be unique (i.e.) if a person with the same email has already been added, this validation check should fail. An AJAX request should be made to check if the email is unique or not.
  • Validation on Graduation Year: Should be in accordance with the age (i.e.) the person must be at least 16 years old during graduation.
  • The form should have a Submit button at the bottom which should get activated only when all validation checks have passed. On clicking the submit button, an AJAX request should be made to add the values provided in input.
  • The second page should simply list all the persons who have been added using the form input in the first page. It is not necessary to use a database, the values can be stored in memory for this simple web application.

The candidate is free to use any JS Framework of his/ her choice (e.g.) AngularJS, ReactJS, EmberJS, BackboneJS, jQuery or GWT etc.

Webcam Monitoring prevents cheating and impersonation

WebCam Monitoring

The candidate is monitored via webcam to ensure that there is no impersonation and that the candidate does not communicate with others in person or using mobile during the test.

Window Proctoring

The test window is proctored. If the candidate navigates away from the test window (for instance, to use google search), multiple warnings are given. If the warnings are ignored, the test is ended immediately and a red flag is raised in the report.

Window Proctoring locks the test window and prevents candidates from switching to other browsers (chat, search etc) during tests
Copy Detection is applicable for coding submissions. We ensure that code submissions from two different candidates are not very similar

Copy Detection

When code submissions by any two candidates are too similar (>85% similarity), a red flag is raised indicating possible code plagiarism.

Random Pooling

Each candidate taking the test can be given a smaller set of questions that are randomly selected from a large pool of questions.

Questions for each candidate are randomly selected from a large pool of questions
