During my onsite technical segment, I was asked to expand on my coding challenge by implementing additional functionality. The engineering manager for the iOS team and the Android team were there to explain the requirements and answer any questions I had along the way.
SWIFT : optional methods in protocols.
Direct Technical Questions and Programming.
Structure data concepts and flows for a service API.
Fix a broken REST API iOS app.
iOS: Concurrency, Persistance, Swift, UIKit, Notifications, Architecture Patterns, and everything around it.
I can't give away the questions but 2 were coding and 1 subjective related to one of the coding problem. 1 DB question and 1 shell scripting. I could complete only 2 and attempted 1 coding. The coding is about scheduling meetings.
