◦ Introductions and past experience ◦ CS Fundamentals and Coding: Question will be of harder difficulty than the question of the screening round and require optimization in memory or performance constraints. You should be able to discuss details of their implementation, and any performance or memory tradeoffs made. ◦ Discussion of programming language concepts: Familiarity of C/C++ and lower level memory management (if not used in the coding exercise). Knowledge of mobile development languages (Java/Objective-C and native code interop) ◦ Q&A
