About

Interviews

Read full description

Interviews is the daily workout for anyone preparing for a mobile developer technical interview. Five questions a day, two minutes, and a path that grows with you. FOUR TRACKS, EACH ON ITS OWN Swift, UIKit, Kotlin and Flutter. Turn on one or all of them: each has its own topics, in the order it makes sense to study them. You start from the fundamentals of the language, never halfway through. THE DAILY QUIZ Five questions tuned to your level, drawn only from the topics you've already unlocked. Answer, read the explanation, keep your streak alive. XP AND RANKS From Junior I all the way to Staff. Every correct answer is worth 10, 20 or 30 XP depending on difficulty, and as your rank goes up the mid and senior topics open up. REVIEW WITH REAL ANSWERS Short lessons with annotated code and, above all, the answer to actually give out loud to the person interviewing you. CORRECTIONS THAT EXPLAIN When you get one wrong you don't just see the right answer: you read why yours was wrong. Your mistakes stay set aside until you fix them. SMART REMINDERS One notification at the time you choose, only on days you haven't done the quiz yet. Never one more. OFFLINE, NO ACCOUNT Interviews works on the subway as well as on the couch. No sign-up, no ads, no tracking: your progress stays on your iPhone. Available in English and Italian.
