2) Have you designed custom data structures such as a hash map or priority queue?  If so, describe the problem you were trying to solve and the solution, highlighting design considerations and trade-offs.

3) Have you designed or developed a system that requires handling high throughput (1000’s of events/updates per second) with low latency (<1 msec per event) with data from multiple sources and potentially with different data formats/messaging protocols?  If so, describe the architecture with emphasis on performance considerations
