So much this. Networking(where you went to school and work) and luck(your country, your nationality, your ethnicity, your skin color, your looks, your accent, being at the right place and the right time) are worth more than your CV and side projects but this is rarely mentioned in this field as it's always touted that tech is a pure meritocracy.

One can often read sour vents on reddit on devs who lose hope, get depressed and burn out after being unemployed or stuck in dead end jobs for so long while they keep grinding leetcode and churning projects on github because the internet told them that SW development is a meritocracy and the key to success is putting enough hard work in your free time even though there's devs coasting on six figure jobs who haven't written a line on github in their life on their free time.

Nope, it's definitely no meritocracy, the tech world is just as unfair as the rest but has much better PR about it: watch Silicon Valley TV series made by the satire comedy genius Mike Judge(Office Space, Idiocracy) where billionaire tech magnate Gavin Belson would always sugarcoat his hostile business decisions with talks of buddhist spirituality, endangered animals and making the world a better place while his true motivation was only the accumulation of more fame, wealth and power.
