One piece of advice I have heard several times is not to treat the meet up as an opportunity to talk solely about yourself. If you find someone that happens to work at a place you’d love to work, rather than swerving the conversation to ‘get me a job there as soon as possible’, ask them what it’s like to work there, what projects they find interesting, what technologies they use, and show a real interest in them and the work.
It’s kinda conversation 101, but lots of people are bad at conversation. If you are the one that allows people to talk about what they love, you will be remembered fondly, and that can’t be a bad networking strategy.
By all means, if they ask you about projects you’ve enjoyed working on, be sure to sell yourself as a passionate problem solver etc…but don’t just go around shaking hands with every one saying what a great guy you are and that they should hire you
