About the Infosys Mobile Engineer hiring loop

Infosys hires through three tracks — Infosys SP (System Engineer, ₹3.6 LPA), DSE (Digital Specialist Engineer, ₹6.5 LPA), and Power Programmer (₹9 LPA). HackerRank-style coding (Java / Python / C++) plus 90-min Aptitude (Quant + Logical + Verbal + Pseudocode).

Mobile rounds score on platform-native fluency, offline-first architecture, performance awareness, and security posture. iOS vs Android role-specific depth is expected; cross-platform breadth is a plus.
