I'm a software engineer, and I get a fair amount of emails from recruiters. I'm happy with my current role (well, not happy, but content at least), so I'm not looking for a new job right now, and say as much in my responses.
But some of these emails close by saying that even if I'm not looking for a new job, they would be happy to have a chat about the project/position if I'm interested.
Should I take them up on this offer? On one hand, I feel like it may give the wrong impression that I actually am open to switching jobs. On the other, it could help me get a wider view of the industry, and learn about certain roles that I may be interested in some time from now.
