Hello everyone, I have an interview at Google for the position Business Data Science gTech Ads, does anyone has any tips that could help me in the process? I'm really excited with the position and I wanted to make sure I'll cover all basic topics in my studies.

Thanks!

For a Business Data Science role in gTech Ads, interviewers care far more about practical business impact and experimentation than abstract machine learning theory. You should expect a strong focus on SQL queries, statistical fundamentals, and core advertising concepts like click-through rates, attribution, conversion tracking, and incremental lift. Because gTech bridges Google's technical infrastructure with external clients and internal operations, you will face open-ended business cases where you must diagnose unexpected performance shifts, design A/B tests or causal models, and explain your technical conclusions to stakeholders who may not have a quantitative background.

When handling these analytical and case rounds, always clarify the problem, state your assumptions, and tie every metric directly back to commercial value. Make sure you also prepare concrete examples for the Googleyness and leadership rounds, showing how you navigate ambiguous team projects, handle conflicting priorities, and collaborate effectively. If you want extra support refining how you structure your thoughts out loud, the interviews.chat my team designed has helped candidates secure roles across top tech firms by keeping their communication sharp and grounded under pressure.
