How to quickly qualify leads at business conferences

So first of all, we have to know how to represent us, maybe with a quick phrase less than 30 seconds, just for people to understand what we do, what's the value that we provide to them and how do we do that? For example, it's simple. As I told before, I'm helping founders of software development companies to find newbie clients via LinkedIn. Very simple. Yeah, you can easily understand. Do you need big lines, yes or no? Do you believe in LinkedIn? Yes or no? And do you work for software development company, yes or no? Very simple one. Right. So that's why just test it for yourself and you will find out how it works and it will save you a ton of time and efforts for that. That's number one. Then of course you see a lot of people in front of you, so you should prepare a list of qualification questions. For example, you need to quickly verify the position of the person. What's the title of the position? What is the person in charge of? Because it is absolutely not necessary to talk to not C level people because they do not make decisions.
