In this section, you’ll find seven tips on how to make the most out of the jQuery interview questions from this article and evaluate applicants accurately and objectively.
Skills tests, such as the jQuery test, should come before interviews. There are a few benefits to this approach. Essentially, it enables you to:
Mitigate unconscious bias when making an initial shortlist of applicants to interview
Speed up hiring by interviewing only your best applicants and getting rid of the lengthy, biased CV-screening process
Accurately compare promising jQuery applicants’ skills with the help of objective data
For these reasons, it’s best to use the jQuery skills test before interviewing candidates. In addition to that, we advise you to use it in combination with other skills tests to gain an in-depth understanding of your candidates’ qualities.
With TestGorilla, you can combine up to five skills tests in a single assessment.
Skills test results provide another advantage for HR professionals: You can use them as a starting point to complete your list of questions.
For example, If some applicants’ technical jQuery skills were weaker, you can include questions related to this in the interview to see if they have the right potential.
Sharing information about your team, the project, and the company is a way to enhance the candidate experience, put them at ease, allay any doubts they may have, and improve your employer brand and reputation. So, use this opportunity to give candidates detailed information about your organization.
Ask the right questions to learn about your applicants’ jQuery experience. Ask questions such as:
How long have you been using jQuery?
Have you used jQuery for any side projects?
What benefits did using jQuery have in your last project?
Responses to questions such as these will indicate how well your applicants understand the jQuery library. This can help you make the right hiring decision.
Begin the interview by asking a few general jQuery interview questions before moving on to more complex topics.
For example, you might ask questions related to projects they have completed using jQuery in their current role to get an idea of how familiar they are with the library. You may also ask about the skills they want to develop and how they intend to work on them.
Take notes of applicants’ responses during interviews. This will help you in a few ways, as it enables you to:
Keep recency biases at bay
Share results with the rest of your hiring team
As a result, making the right hiring decision will be much easier.
You’ve now got a head start for onboarding and training your next jQuery expert: Use test results to tailor your onboarding process to them and determine which training programs will best help them develop their skills and deepen their knowledge.
Hiring the right jQuery professionals isn’t an impossible challenge. When you use TestGorilla to build and administer skills assessments, you’ll be able to streamline and shorten the recruitment process – and also eliminate bias.
So, use our jQuery test in combination with other skills tests relevant for the role to identify the candidates who meet your requirements and invite them to an interview.
