Beyond technical acumen, successful candidates demonstrate strong architectural and design pattern knowledge (MVVM, MVI, Clean Architecture), a performance-first mindset, and the ability to diagnose and resolve complex technical issues across the entire stack. Excellent problem-solving skills, proactive ownership of projects, and effective communication are essential soft traits.
