7 tips for incorporating these GCP interview questions into your hiring process

Before you start interviewing highly-skilled applicants, we have seven tips on how to successfully incorporate GCP interview questions into your hiring process.

7 tips for incorporating these GCP interview questions into your hiring process

1. Use skills tests before interviews and after candidate sourcing

Using skills tests yields the best results if you do it before you conduct interviews and after you source applicants. With TestGorilla, you can combine up to five skills tests in a single assessment, and we have a vast test library to choose from. 

This way, you can reliably assess candidates’ soft skills and technical expertise and only focus your attention on the ones who meet your hiring criteria for the role.

So, create a skills assessment and invite all applicants to take it as soon as you receive their applications. To shortlist applicants, you simply need to look at test results.

2. Think of the interview as an opportunity to exchange information

When interviewing applicants, consider it a chance to exchange information with applicants. Otherwise said, look at the interview as a two-way process in which you can find out more about prospective employees, and in which they can discover your organization and see if it’s the right fit for them.

To effectively exchange information with your applicants, begin by providing them with enough information about your open role and the organization as a whole. Inform them about the team and give them details about the projects they’ll be working on.

You can then ask your applicants for information about their skills and GCP experience. Don’t forget to complete the interview by inviting applicants to ask any questions they may have. Prepare to answer their questions and give them detailed information to enhance the candidate experience.

3. Consider the advantages of structured interviews when asking GCP interview questions

For the best results when interviewing applicants, we advise you to use structured interviews. This process involves asking every applicant the same set of interview questions in the same or similar order. You don’t need a rigid script, though: Asking follow-up or clarification questions is definitely still okay (and advisable). 

Using structured interviews has many advantages: Not only can you guarantee that you’ll make the process fair and more consistent, but you’ll also find it easier to compare applicants’ responses to your GCP interview questions.

Another crucial advantage of structured interviews is the fact that this is a legally defensible interview method. Since you’ll ask all applicants the same questions and can establish objective criteria for hiring applicants, structured interviews are the top option that many companies choose (including Google, by the way).

4. Take notes during interviews

Later, when you’re done with the interview stage, you’ll need to compare your findings with the rest of your team. To keep track of your findings, take notes during the interview. There are a couple of methods you can use to make note-taking less uncomfortable for your interviewee.

First, always let your applicant know that you’ll take notes. Explain the purpose of your note-taking before you proceed with the interview.

Second, try to keep eye contact with your interviewee when you’re not taking notes. Try not to focus entirely on the paper or document on which you’re writing, and ensure that your focus doesn’t detract from the interviewee.

5. Review your applicants’ skills test results and interview responses

When you’ve completed all the interviews, you can now look at your applicants’ responses to your GCP interview questions and the skills tests in combination. 

Picking the right applicant doesn’t have to be complicated. Top skills testing platforms like TestGorilla will calculate your applicants’ results automatically, and the notes you’ve taken during interviews will facilitate the decision-making process. 

Compare your applicants’ test scores with your interview notes and discuss these results with your hiring team.

6. Offer feedback to professionals whose skills don’t match your open position

There are a couple of critical reasons you should offer feedback to GCP professionals whose skills don’t match your open position. The main advantage is that it enhances the candidate experience and your company’s reputation. Essentially, it benefits your applicants and your organization at the same time. 

The second advantage of offering feedback is that your applicants may choose to develop their skills and then re-apply for a future opening with your organization. The feedback will give your applicants the chance to develop the GCP skills they lack and apply later. 

7. Design training and onboarding by reflecting on skills tests and interview responses

Do you struggle to develop the right training programs for new hires? 

The best way to handle this phase is to use what you’ve learned about new hires throughout the hiring process. Revisit skills test results and create programs that are a good match for the candidate you’ve hired.

When should you use GCP interview questions in the hiring process?

GCP interview questions are best used after you have given applicants a GCP skills test. 

Armed with skills test results, you’ll have no problem shortlisting candidates for an interview; all you’ll need to do is check the results and select candidates based on their experience and knowledge. 

In other words, source candidates, invite them to complete a GCP skills test, and interview the best applicants by using the GCP interview questions from this article.
