iOS interview preparation plan
Good preparation is about sequencing, not cramming everything. Here is how to spend your time depending on how much of it you have.
With four or two weeks
With four weeks, rotate through the core areas: Swift and concurrency, SwiftUI and UIKit, architecture, and mobile system design, doing a little live coding out loud every day and one mock per week. With two weeks, narrow to your weakest areas and the rounds your target company emphasizes, and keep practicing narration, since communication is what most people neglect.
With only a few days
With a few days, do not try to learn new topics. Rehearse the live coding process, clarify then narrate then test, review concurrency and memory management quick-reference points, and prepare three or four behavioral stories in STAR form. Sleep and calm matter more than one more topic. Walking in composed beats walking in exhausted.
Go deeper than a summary
Share Your Screen works topics like this through in full: 75 solved Swift problems with tests, 9 real case studies, and 7 annotated mock interviews, so you rehearse the live round instead of just reading about it.
Frequently asked
How long do I need to prepare for an iOS interview?
Four weeks is comfortable for broad coverage, two weeks works if you target weak areas, and a few days should focus on process and review, not new topics.
What is most overlooked in prep?
Practicing communication and the live coding process out loud. Most candidates study topics but never rehearse narrating and recovering under observation.
