Common BI Architect Interview Questions

What does your ideal data architecture look like?

There are a few reasons why an interviewer would ask this question to a BI Architect. First, the interviewer wants to know if the BI Architect has a clear vision for what an ideal data architecture would look like. Second, the interviewer wants to know if the BI Architect has the technical skills and knowledge to design and implement such an architecture. Third, the interviewer wants to know if the BI Architect is familiar with the latest trends and technologies in data architecture. Finally, the interviewer wants to know if the BI Architect is able to articulate his or her vision in a clear and concise manner.

Example: “My ideal data architecture would be one that is highly scalable, flexible, and easily accessible. It would allow for real-time data analysis and would be able to handle large amounts of data. The architecture would also be easy to maintain and would provide users with the ability to easily query the data.”

Example: “I have designed and implemented a data warehouse before using the Inmon methodology. This involves creating a central repository for all data, which is then accessed by various reporting tools. I have also used the Kimball methodology, which is based on dimensional modelling. This approach involves creating a star schema, with a central fact table surrounded by dimension tables.”

What is your experience with data mining and predictive analytics?

The interviewer is trying to gauge the BI Architect's understanding of data mining and predictive analytics, and whether they have experience working with these tools.

By asking about the details of how the BI Architect designs ETL processes, the interviewer can get a better sense of what they would be like to work with on a day-to-day basis.

Example: “There are a few key steps that need to be followed when designing ETL processes:

1. Understand the data sources that need to be integrated. This includes understanding the structure of the data, as well as any relationships that exist between the data sets.

2. Define the target data model. This is the format that the data will be stored in once it has been extracted, transformed, and loaded into the destination system.

3. Design the extraction process. This involves specifying how data will be extracted from the various source systems.

4. Design the transformation process. This involves specifying how the data will be transformed from its original format into the target data model.

5. Design the loading process. This involves specifying how the transformed data will be loaded into the destination system.”
