Answer first
You answer in your own words, before you see anything. Your first attempt is kept exactly as you wrote it.
Walk into your senior iOS or Android loop with answers that hold.
Interviews are decided at the follow-up. Interview Runtime trains that moment: you answer, see the one gap that would have cost you the point, then answer again when one fact changes.

From readers of the book
What readers of the interview books wrote
This book is exactly what I was looking for.The sections on modularization, Swift internals, architecture trade-offs and system design felt much closer to real senior-level interviews than anything else I've read. Most interview resources focus on the right answer, while this one helped me understand the reasoning and depth behind it
Every explanation of different answer levels helped me understand the gap between a correct answer and a strong senior-level answer.
I've been doing Android for 6 years, and this book made me feel like I was discovering Android again. So many interesting questions and topics that made me stop and think. Highly recommended.

How Interview Runtime works
See the gap that costs the point
It finds one gap that would have cost you the point, not fifty that would not.
Answer again when one fact changes
Then it changes one fact and asks again, because that is what the interviewer does.
Every session leaves evidence.
One mission from the iOS route, start to finish, recorded in the product. Nothing retyped for the camera.
One question, scored the way a senior round is scored.
What you train
Built for the moment the interviewer changes the question.
Your first answer, kept
The baseline stays exactly as you wrote it, so every later answer is compared with the real starting point.
One consequential gap
Not a score on fifty criteria. The one thing that would have cost you the point, quoted from your answer.
The changed constraint
One fact changes, the way it does in the room. The answer has to adapt, not repeat.
Evidence, side by side
Both attempts next to each other, and which criteria moved from missing to established.
Twelve simulations
Timed interview events per platform, with a candidate brief and a constraint revealed during the attempt.
The book and code to keep
The platform book as PDF and EPUB and the companion code, yours after the 90 days end.
Why Interview Runtime
More questions will not fix it.
You can read three hundred answers, recognise every one, and produce none of them. Knowing a system and retrieving it under pressure are different skills, and only one of them gets tested.
Question banks

Interview Runtime
- You answer first, in your own words
- One fact changes, the way it does in the room
- Progress means an answer that changed
- Every attempt preserved, side by side
- The gap comes from your own answer
From readers of the book
What readers of the earlier books say.
Reviews of Mike Salari's earlier interview books. They pre-date Interview Runtime and its Guided Practice. More reviews on salari.dev
“Most iOS interview books stop at 'here's the answer.' This one shows you the entire conversation: the interviewer's follow-ups, where candidates stall, and what a strong recovery looks like.”
“It's become my go-to starting point whenever I'm preparing for iOS interviews.”
About the author
I watched strong engineers lose interviews for reasons nobody explained to them.
After enough interview debriefs, the pattern became difficult to ignore. Strong engineers often did not need another hundred questions. They needed to know what an interviewer could observe, score and defend in the hiring meeting. Experience across Apple, Adobe, Cisco, Mastercard and Visa, including fintech and regulated systems where correctness and security are not optional.
