Non-technical people are now generating massive amounts of data code through AI agents instead of waiting for BI teams, but this code lives everywhere—scattered across chats, laptops, and Slack—with no way to verify accuracy, reproduce results, or enforce standards. Traditional BI tools can't fix this because they're too rigid, leaving data teams stuck between chaos and lockdown.

• Millions of non-technical users are writing billions of lines of AI-generated code for analytics, replacing the old ticket-and-wait model with instant answers—and nobody wants to go back.
• The generated code is ungoverned and untraceable: there's no record of what context the AI used, which tables it queried, or what filters it dropped, making it impossible to verify if the numbers are actually correct.
• Data teams face a false choice: either let people generate whatever they want and abandon governance, or force them back into rigid BI tools that can't do much of anything.

This article lists 30 important interview questions for Business Intelligence Engineering roles, focusing on skills relevant in the AI era. It aims to help both candidates and interviewers navigate the evolving landscape of data and analytics.

• The article compiles 30 BI engineering interview questions specifically framed around how AI is reshaping the role, not just traditional BI skills.
• It pushes beyond tool-specific knowledge (SQL, Tableau, Power BI) to test how candidates reason through data governance, integrity, and security issues.
• It frames machine learning familiarity as now a baseline expectation for BI engineers, not a separate specialty.
• It stresses evaluating soft skills like translating technical findings into business insights for cross-functional teams as equally important as technical chops.

This article explores the evolving role of data engineers over the past 50 years, highlighting their often unnoticed contributions to data infrastructure. It discusses the challenges they face, such as managing dependencies and schema changes, while emphasizing that the core problems remain unchanged despite new tools and technologies.

• The core problems of data engineering—dependencies, integration issues, schema changes—haven't changed in 50 years despite new tools like dbt, Iceberg, and cloud warehouses.
• Data engineers are invisible when things work but instantly blamed when something breaks.
• Real-time data requests are often unjustified since almost no one can explain how a 10-minute delay would actually change a decision.
• Industry growth reflects better marketing and rebranded terminology more than genuine advances in solving data management problems.

Since the inception of SQL in 1974, there has been a recurring dream to replace data analytics developers with tools that simplify the querying process. Each decade has seen innovations that aim to democratize data access, yet the complex intellectual work of understanding business needs and making informed decisions remains essential. Advances like AI can enhance efficiency but do not eliminate the crucial human expertise required in data analytics.

• SQL was designed in 1974 by IBM's Chamberlin and Boyce specifically to let non-programmers query data in plain English, yet this self-service dream has resurfaced every decade (OLAP in the 80s, semantic layers now) without ever eliminating the need for developers.
• AI can now generate SQL and build analytical models faster than ever, but it automates only the mechanical coding, not the judgment calls about which metrics or definitions actually matter.
• The real bottleneck was never syntax or tooling but the intellectual work of understanding business context — a gap AI accelerates around but doesn't close.
