I am sure college grads (from decent Indian colleg) can solve this one. The problem is they have done leetcode style of puzzles all their college life. - mostly control flow, numbers and DP / greedy / graph patterns. Which is such narrow area of computer science. They don't understand basics of - operating systems (eg: VMs), compilers (eg: compiled vs source code, optimization), languages (eg: type systems), networks (eg: NAT, firewall), software engineering (eg: writing modular code, version control). All these things are as Computer Science as leetcode algorithms. These are in the syllabus, at least in a primitive form. But these kids are only tested on leetcode puzzles. Ask anything deep on these and watch these DSA-generation kids struggle.
