There is no easy way to determine how good their tech talent is especially in programming skills. It’s like finding a needle in a haystack. Many software developers proclaim that they can code, but how good they are in programming? Only after they’ve hired, then we will know how their performance is. If the hired turn out to be a bad programmer, they gave us issues such as project delay nor technical debt which would cost us a sum of money. According to Tony Hsieh of Zappos, the real cost of hiring a bad software developer cost that company more than $100 million.
