How were integrations handled?

Practice this question
Discussion template: use your own project facts, ownership, and measured outcomes. Bracketed text is a placeholder.

Short explanation:

An integration connects your system to an external provider with its own data format, identity rules and availability. A good answer covers both data mapping and operational behavior such as timeouts and rate limits. The integration boundary is where many partial failures and mismatched assumptions appear.

Key points:

  • Name the provider, exchanged data and actual trigger: request, webhook or schedule.

  • Explain how the real implementation handled credentials, failures and limits.

  • Explain whether your app pulled data, received a webhook or initiated an external action, and what happened when the provider was unavailable.

Interview point:

  • Name the source of truth and how external IDs were related to internal records if that was part of your work.
