Top 5 Dependencies Interview Questions

Browse 5 real-world technical and behavioral interview questions about Dependencies. Review scenarios, edge cases, and architectural best practices.

Tell me about a time another team was blocking you and you had no authority over them.

Show that you understood the other team's priorities before deciding they were unreasonable, that you made the cost visible in their terms and in writing, that you offered to absorb some of the work, and that any escalation went through their manager with them present.

For three sprints running your team has lost most of a week waiting for a shared test environment another group controls. What do you do about it?

Price the delay in developer-days from the board's own timestamps, then escalate with a specific ask, an owner and a date rather than a complaint. Decide honestly whether this is an impediment somebody can remove or a constraint to design around, and watch for the workaround that hides the cost.

You have six teams building one product and they keep blocking each other. How do you coordinate the dependencies, and what do you make of frameworks like SAFe?

Reduce dependencies before coordinating them, by moving team boundaries towards whole slices of value and replacing synchronous handoffs with contracts. Coordinate what remains with a visible dependency board and one ordered backlog. SAFe buys alignment and a planning cadence at real cost in batch size and process.

You add one small npm package to a service. What have you just taken on?

Not one package but its whole transitive closure, install-time scripts from every node in it, a build that now depends on the registry being reachable, and the possibility of two resolved copies of the same library whose instances fail each other's identity checks.

You promise 99.9 percent availability and you call five services that each promise the same. What have you committed to?

Nines only mean something as a downtime budget over a stated window, and dependencies in series multiply: five hard dependencies at three nines each put your own ceiling near 99.4 percent, so the target is met by removing dependencies from the critical path rather than by asking each owner for more nines.
