I collected the algorithm and example we may need during the system design on https://github.com/resumejob/system-design-algorithms Frugal Streaming Geohash / S2 Geometry Leaky bucket / Token bucket Loosy Counting Operational transformation Quadtree / Rtree Ray casting Reverse index Rsync algorithm Trie algorithm Check out the examples on the repo.

Algorithm Collection Q1: How would you find a cycle in a linked list? Try to do it in O(n) time. Try it using constant amount of memory. Q2: Given a history of URLs, how would you determine if a particular URL had been seen before? Q3: Since pages can have multiple URLs pointing to them, how can you make sure you've never seen the same CONTENT before? Q4: Come up with the plan on how to traverse a graph, as well as to quickly determine if a given URL is one of the million or so you've previously seen. Q5: The Web can be modeled as a directed graph. Come up with a graph traversal algorithm. Make the algorithm non-recursive and breadth-first. Q6: Write a function to print the Fibonacci numbers Q7: Write a function to print all of the permutations of a string. Q8: Design a memory management scheme. Q9: Give a one-line C expression to test whether a number is a power of 2. Now implement it without using loops. Q10: How can I swap two integers in a single l...

I think the intervier was more realistic than the other two . Not just because he recommend to 2nd interview, since I also have the experience with recuriting other employees in the past. I felt the potenial is more than anything in work. Coding is j...
