I've had several companies make offers to me based on my resume and online presence. At first glance, they're a very mixed bag; some very exciting offers from good looking companies and some that feel like lame cold calls.
When I am contacted by an employer unsolicited, should I assume they are likely cold-calling a large range of people? For obvious reasons I only want to continue the conversation with employers actually interested in me and my skills, how. How can I tell when an unsolicited offer is backed by real interest instead of blind reaching?
