iOS Developer Interview Questions
Have you ever used test- or business-driven development?
Suggested approach: Hopefully the answer is yes, even if only a little, but remember to give examples. Did you use TDD/BDD fully, or did you occasionally write tests later on? Did you use it as part of a larger team? Did you find that it helped or hindered you from building a great product?
You might find it useful to talk about your approach specifically, because everyone is different.
Estimated difficulty: Intermediate

Important notes
- There are over 150 interview questions in the system. Once you've read the question and come up with a suitable answer, try reading my suggested approach and see if it helps you add more detail.
- These questions are not designed to be hard; a good interviewer is more interested in generating discussion that lets your ability and interests shine through.
- If you answer a question with "yes" or "no" you've missed the point – interviewers prefer you to provide reasoning, explanation, or detail, so try to elaborate with examples!
- If you're looking for detailed technical questions about the language, you should try my Swift tests instead – there are multiple challenges that will work your brain hard.
- For a whole series of coding challenges, I wrote the perfect book for you: Swift Coding Challenges.
