About the IBM Mobile Engineer hiring loop

IBM's hiring spans pure tech (research, cloud) and consulting-style (IBM Consulting). Tech rounds are moderate-difficulty coding plus enterprise architecture. Consulting rounds include case interviews and stakeholder-management scenarios.

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.
