Question 1

What is iOS Interview Platform?

Accepted Answer

iOS Interview Platform is an interactive platform for iOS developers to practice for technical interviews. 700+ questions covering Swift, UIKit, SwiftUI, GCD, Concurrency and architecture across 5 difficulty levels from Junior to Architect.

Question 2

What difficulty levels are available?

Accepted Answer

5 levels: Junior (Swift Basics, UIKit, MVC), Middle (Protocols, GCD, MVVM, Networking), Senior (Concurrency, Architecture, Testing), Architect (System Design, Scalability, Team Processes), and Custom (real questions from iOS interviews at top tech companies).

Question 3

Is it free?

Accepted Answer

Junior is completely free without registration. Middle, Senior and Architect are free once you sign in with Google or LinkedIn. The Custom level (real interview questions) and ATS Score are in early access - join the waitlist and we grant access for free as soon as we open it up.

Question 4

Does it work offline?

Accepted Answer

You can install it as a PWA (Progressive Web App) and add it to your home screen, and the interface loads instantly on repeat visits. Taking a quiz, though, needs an internet connection - answers are checked on the server so the answer key never reaches the browser.

Question 5

What quiz modes are available?

Accepted Answer

Three modes: Quick (10 questions, ~10 min), Full (30 questions, ~30 min) and Marathon (100 questions, ~90 min). Marathon unlocks AI feedback in Junior, Middle, Senior and Architect sections.

Question 6

Is there a timer?

Accepted Answer

60 seconds per question. The faster you answer, the higher your speed bonus - simulating the pressure of a real interview.

Question 7

What is in early access?

Accepted Answer

The Custom level (real iOS interview questions from major tech companies) and ATS Score - a tool that scores your resume against a specific job description with a per-criterion breakdown. Everything else (Junior–Architect, AI feedback in Marathon) is free and open.

Question 8

Do I have to pay?

Accepted Answer

No - early access is granted for free. The project runs on AI tokens that cost money, so it lives on voluntary donations, but donating is optional and does not affect your access.

Question 9

How do I get access?

Accepted Answer

Sign in and click "Get early access" - you join the waitlist. We open access in waves and grant it manually, for free. If you would like to support the project, you can donate any amount using the payment options shown there (entirely voluntary).

Question 10

Is there a subscription to cancel?

Accepted Answer

No - there is no subscription and no recurring charge. Access is a free grant, and any donation is a one-off, voluntary contribution.

Question 11

How does AI feedback work?

Accepted Answer

After completing a quiz, the platform uses AI to analyze your answers and generate a personalized report styled as a Tech Lead evaluation: strengths, areas for improvement, and specific topic recommendations.

Question 12

When is AI feedback available?

Accepted Answer

AI feedback needs a full 100-question session: it appears after any Custom section (real interviews) or after a Marathon (100 questions) in Junior, Middle, Senior or Architect. If a Marathon comes up with fewer than 100 questions - optimization hides questions you already answered correctly, so a repeat run can fall short - reset optimization to bring them back, and a full 100-question Marathon unlocks feedback again.

Question 13

How do I report a problem with a question?

Accepted Answer

During a quiz, each question has a "Report" button at the bottom. Click it, select the reason (incorrect answer, wrong level, bad translation, etc.) and optionally add a comment.

Question 14

What happens after I submit a report?

Accepted Answer

The report is sent to our team. Questions with frequent reports are reviewed and corrected or removed as needed. Thank you for helping improve the platform!

Question 15

What are likes and dislikes for?

Accepted Answer

Likes mark a question as a favorite. Dislikes mark a question as unwanted - disliked questions stop appearing in your quizzes, helping you focus on relevant topics.

Question 16

How do I reset / clear disliked questions?

Accepted Answer

Go to the "Session History" section and click the "Reset dislikes" button - all disliked questions will appear in quizzes again. Useful when switching to a new preparation topic.

Question 17

What is optimization?

Accepted Answer

Optimization remembers questions you answered correctly and stops showing them in future quizzes, so you focus on new and previously-wrong questions. It works automatically - every correct answer is saved locally in your browser. Questions you got wrong or skipped keep appearing.

Question 18

How do I reset optimization?

Accepted Answer

Go to "Session History" and click the "Reset optimization" button - all correctly answered questions will appear in quizzes again. You can also reset it from the screen that shows up when every question in a section has been solved.
