It may be useful to remember that the author lives in France and has spent his whole professional life in France. As a French having worked in Germany, Canada and New Zealand, I can say that the recruitment process is very different in other countries, where side projects and open source contributions are really valued. In my opinion, his article should mention the geographical setting of his experience, and his advice should only apply to people living in France (and writing the article in French may have been more appropriate too)
