So whoever hired the guy should feel bad. He explains the strategy to boost his payroll, he was hiding the bootcamp he was attending and he was showing himself as experienced dev. And also why would you hire someone if 300 other companies were not interested in that person?
Ironically his lack of experience shows itself even in the first fancy function he writes on the blog post. Would not this unnecessary if block be a red flag in a coding interview?
I am sorry to see this type of people in the industry and I am sure I would do the best to not to let such people getting hired in my teams.
