The fizzbuzz syndrome is real alright. But someone failing fizzbuzz is not an indicator that they will always be incapable of development. It just means they are very junior and require training. Frighteningly for the West, Indian and Chinese companies appear to grok this and actually develop their employees. US and UK companies throw their hands up in empty self-satisfaction that their work is so intellectually difficult that people up to the challenge are impossible to find. The reality is probably that the corporate business model is flawed meaning they cannot afford the seniority of guy they need.
