built a mobile only interview prep site. missing anything obvious?
so when i originally wanted to leave my first ios swe job i found that mobile interviews feel weird compared to generic swe prep. backend engs have a much easier time because they follow a more well defined, paved loop that mirror new grad interviews.
on the mobile side half the loop is stuff like lifecycle, concurrency, "build this small app in an hour", debugging a janky project, and mobile flavored system design. not just invert a binary tree on a whiteboard which i spent hours prepping for and only was a small part of the overall interview process.
in order to figure it out i cold dm'd a ton of random ios engineers and barely got any responses + i failed my first 5 interviews just to get the hang of it. i kept bouncing between random blog posts, leetcode, and youtube so i put together something for myself and figured i'd share it in case it helps anyone else prepping.
it's called acemobileinterview. ios + android tracks with:
- general fundamentals + algorithms (free)
- timed xcode / android studio style projects
- buggy starter zips for debugging practice
- system design + behavioral stuff
i'm not trying to spam this everywhere and also genuinely curious what you'd add or cut if you were prepping for a mobile loop right now.
site: acemobileinterview.dev
happy to answer questions about how i structured it or what's in the ios vs android tracks. for context i've been an ios engineer for 6+ years and have made several job switches + gotten offers from netflix, duolingo, patreon, + many more
