1.) Algorithm Complexity: You need to know Big-O. If you struggle with
basic big-O complexity analysis, then you are almost guaranteed not to
get hired.
For more information on Algorithms you can visit:

2.) Coding: You should know at least one programming language really
well, and it should preferably be C++ or Java. C# is OK too, since
