★★★★★
I've bought many iOS interview books, but they're all far behind this one ☝️. What I love most is that Mike shares his real experience instead of just listing questions and answers. It's practical, easy to follow, and feels like advice from someone who's actually been through these interviews. I'm still preparing for my interviews, but this book has already changed the way I think about live coding sessions. I've always struggled with explaining my thought process while coding 😭, and this book really opened my eyes to how to approach problems, communicate my reasoning clearly, and avoid turning the session into complete chaos ❤️. Amazing resource! I highly recommend it!!!
