When someone claims they're "good in C," but their idea of writing code is literally arranging the letter 'c' to spell "Hello World." That's like saying you're fluent in Spanish because you can order a burrito at Chipotle.
The painful irony is that actual C "Hello World" is just a few lines that any first-year student could Google in 5 seconds:
#include <stdio.h>
int main() {
printf("Hello World");
return 0;
}
Yet here we are, watching someone flex their ASCII art skills instead of basic syntax knowledge. Classic interview self-destruction.
