Senior iOS take-home interview

At senior level a take-home is judged less on whether it works and more on the judgment the code reveals. The bar is production quality, not feature count.

What raises the bar

Seniors show clean separation of concerns, dependency injection for testability, and a design that would extend without a rewrite. They scope deliberately, cut the right corners, and document those choices. Error handling, empty and edge states, and a few well-aimed tests are present because they reflect how the person actually ships.

How to signal seniority

Treat the README as part of the deliverable: explain the architecture, the trade-offs, and what you would do with more time or in production. Keep the diff focused and readable, avoid gold-plating, and make the core logic testable and tested. The overall impression should be a small, coherent slice of a codebase you would be happy to maintain.

Frequently asked

How is a senior take-home different?

It is judged on architecture, testability, and scoping judgment rather than feature count. Reviewers look for production-quality decisions and clear trade-off reasoning.

Should a senior take-home be bigger?

No. Keep it focused. A small, coherent, well-tested slice with a clear README signals more seniority than a large, unfocused submission.
