The best advice I've had on interviewing is: Find an actual problem that your team is actually working through and ask the candidate how they would approach it.

Then to jazz it up: simplify the proble. To get to the root stuff that needs to be covered (e.g. ignore creating Jira tickets and focus on connecting to a database with cross-refion replication). You also want it to be simple enough that it can be solved in <30 minutes
