Tell me about some projects you worked on where you made an impact
During Algorithmic interview at first I was asked about common things related to Computer Science: - what happens when user inputs query in the browser and presses Enter. This leaded us to DNS, 7 OSI levels, https/http, TLS, TCP/UDP connections, json/xml - how HashMap works and what's the time complexity of adding/getting an element. This leaded us to hash functions and collisions - OOP, inheritance and composition (advantages and disadvantages). The second part was the algorithmic task itself: "You are given an array A of non-negative numbers and a target sum S. Write an efficient function that finds one continuous sub-sequence of elements which sum up to precisely S. The return value should be a pair of array indices or an empty array."
Describe the architecture decisions you made in your project and why
Basic routing and switching stuff. If you’re CCIE you can answer these questions in middle of night in your sleep.
Only technical questions, mostly about multi thread understanding, logic and and Swift under-hood understanding
