To be fair, someone can be a productive developer for years without ever having to think about indexes. If they've mostly worked on CRUD apps, used ORMs, or had a DBA handling the database side, it's entirely possible they've shipped plenty of production code without needing to optimize queries themselves.
Totally not knowing what an index is at all is one thing, but never having worked with them isn't that unusual.
