Maximizing Your Qlik View Interviews: 3 Essential Tips

Before you begin implementing what you've learned, here are three tips to enhance your Qlik View interview process for optimal candidate evaluation.

1. Incorporate Skills Tests Prior to Interviews

Using skills tests before interviews is an effective way to gain insights into a candidate's capabilities. This approach allows you to filter candidates based on their actual skills rather than just resumes.

For Qlik View roles, consider using assessments like the QlikView Online Test and the Data Analysis Test. These tests evaluate core competencies and provide measurable data on each candidate's proficiency.

Implementing these assessments in your hiring process helps you identify top talent early on while streamlining your interview process by focusing on the most qualified candidates.

2. Compile Targeted Interview Questions

You won't have the time to ask every question, so it’s crucial to select the most relevant ones to assess candidates effectively. Tailoring your questions can maximize your chances of evaluating candidates across essential skill sets.

In addition to Qlik View-specific questions, consider including related technical questions from databases, data modeling, or even overarching soft skills such as communication and teamwork.
