Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you had to get business and technical teams to agree on a shared definition for a data concept that everyone used differently. What did you do when they pushed back?
What they are checking: real experience mediating between business and technical stakeholders on data meaning, and skill handling disagreement
Tell me about a time your semantic model or data definition work was rejected or ignored by a business team. What happened and what did you do next?
What they are checking: resilience and ability to learn from pushback rather than just claiming success stories
Describe a project where you had to work across data architecture, engineering, governance, and business teams at the same time. What was the hardest part of keeping everyone aligned?
What they are checking: cross-functional collaboration skill given the role sits at the intersection of many teams
What would you do
Say you're mapping data from a loan origination system and a core banking system into one shared taxonomy, and the two systems have fields that look similar but mean subtly different things. How do you approach that mapping?
What they are checking: practical judgment in resolving semantic mismatches, a core daily task in this role
If you found out an AI or search tool built on top of your semantic model was returning wrong or confusing results, how would you go about diagnosing whether the problem is in the model, the data, or the application layer?
What they are checking: troubleshooting skill and understanding of how semantic frameworks feed downstream AI applications
If leadership asked you to prioritize either broad coverage of many data domains quickly or deep, accurate modeling of a few critical domains, how would you decide and how would you explain that tradeoff to them?
What they are checking: ability to make and justify prioritization decisions under real business constraints
About the work
Walk me through how you would build an ontology or semantic model for something like 'customer' or 'account' when different systems across the bank define those terms differently.
What they are checking: whether the candidate can actually design a semantic model that reconciles conflicting business definitions, not just talk about theory
What semantic web standards have you actually used, like RDF, OWL, or SPARQL, and can you describe a specific case where you applied one of them?
What they are checking: depth versus buzzword familiarity with semantic web technology
Have you worked with a graph database like Neo4j? Tell me about the structure of a knowledge graph you built and why you modeled the relationships the way you did.
What they are checking: hands-on graph modeling experience versus surface knowledge of the tool
How would you design metadata standards that also help this bank meet regulatory compliance requirements, like something tied to BSA or data lineage rules?
What they are checking: understanding of how metadata and governance work connect to real regulatory obligations in banking
Explain lineage tracking to me the way you'd explain it to a business stakeholder who has never heard the term.
What they are checking: ability to translate technical governance concepts into plain language for non-technical partners
What is the difference between a taxonomy, an ontology, and a knowledge graph, and when would you choose to build one over the other?
What they are checking: whether the candidate genuinely understands the distinct concepts named in the job description rather than using them interchangeably
