I think this method doesn't work in all situations. For example in embedded programming. First there are not many of those who actually work in this field so unlikely to just meet up with them. Most are stabily employed. Secondly, there is lots of proprietary hardware and knowledge. Third, hard to work on a trial job when you are already working. Lastly there are a good number of people who are just not skilled enough and will waste your time during the trial period.
