5 tips for using Ionic Framework interview questions

1. Forget resume screening – use skills testing instead

Resume screening is not an obligatory step in the hiring process. There’s no need to screen resumes if you choose to use skill testing, which is much faster and more objective.

When using skills testing, send an assessment to candidates as soon as you receive their applications. Waiting until you’ve interviewed an applicant will slow down your hiring process, which can be counterproductive.

Remember to feature an Ionic Framework test in the assessment, along with other role-specific tests. You can even use a Culture Add test to evaluate cultural alignment or other personality and culture tests.

2. Ask your programmers to outline their Ionic Framework experience

Get a general idea of your programmers’ Ionic Framework experience before you ask them more complex interview questions.

This approach will give you an idea of their general knowledge, help you to see if their experience and skills align with your business’s goals, and also put them at ease. 

3. Give your applicants information about the role

After you ask your applicants to describe their Ionic Framework experience, give them information about your open role. Explain what your business uses Ionic for and give them information about the work of your team and some of your next key goals. 

4. Ask follow-up questions when necessary

When you receive short answers, don’t be afraid to ask follow-up questions. This method will help you determine whether your candidate is just nervous or doesn’t have the knowledge required for your open role.

For example, if you ask your programmers a question about reducing the size of Ionic apps and they only list two methods for doing so, you may ask, “Are there any other methods that can help make an app lighter?”

5. Use test results and notes from interviews to offer feedback – and provide a tailored onboarding experience to the right candidate

After you make a hiring decision, let other candidates know that you haven’t retained their applications. You can use your interview notes and test results to offer feedback to unsuccessful applicants.

As for your new hire, you can begin onboarding them and get them started on small projects. Use their test and interview results to tailor the onboarding process to their needs – this will help them get up to speed and start contributing to the team faster.

If you need help with the onboarding process, you can use an onboarding checklist to ensure you’re not forgetting anything.
