Detailed Interview Plan for a Business Intelligence Analyst

With the key skills in mind, this plan will help you set up your interviews effectively:

Round 1: HR Screening (30 minutes)

In this round, you’ll assess the candidate’s overall fit for the role by reviewing their background and experience. Start by discussing their previous work experience, focusing on relevant roles and accomplishments in business intelligence and data analysis. This will help you gauge their practical experience and achievements.

Next, evaluate their communication and interpersonal skills. Ask about their familiarity with business intelligence (BI) tools and data analysis techniques to determine their technical foundation. Finally, verify their understanding of the job requirements and expectations to ensure alignment with the role. Look for candidates who can clearly articulate their experience and demonstrate a strong fit for the position.

Round 2: Technical Interview (1 hour)

This round focuses on assessing the candidate’s technical expertise in SQL, databases, data warehousing, and BI tools.
