During networking events, what questions can I ask to build meaningful relationships that also keep conversations going for along time?

Great question! Here are some example questions:

1. What do you do? - After some small talk, just ask them directly about their work! Usually, they'll answer with something that'll prompt more questions like "oh, what is [thing they mentioned]?" or "how has [project they mentioned] been going?
2. What do you enjoy most about your job?
3. What's the most challenging part about your job?
4. How did you get into this field?
5. If you could go back and do anything different in your career path, what would you change?
6. How do you see this field changing in the next 5-10 years?
7. What do you do on a daily basis? What does a typical day look like?
8. What advice would you give someone who is considering this type of job (or field)?

Google "good questions for informational interview" and you'll get some more great questions!

The best questions to ask during networking events, are the questions you ask the person about themselves. Examples would be "What do you like most about your job?" or "How did you come about doing what you do?" When you ask someone a question, an important thing to do is LISTEN to their answer and look them in the eye when talking with them. Show interest in their answer and ask follow-up questions to keep the conversation going.

Hi Brian, as mentioned above make sure it has to do with the person in question (but not too personal) and do ask open ended questions. That will enable you to drive the conversation in multiple different directions/ areas based on the answer. One more tip: ask the question in a way that will help you understand that person's core values. Understanding what they are all about , what's driving them (core values) can help both of you feel like you got to know each other and relate to one another. Hope it helps

What a great question! The key is to focus on the person you are networking with, at that moment. A somewhat different, yet positive way, to start a conversation is: What is going very well for you today?" The person will let you know something positive as a way to get started. Once the conversation is going, continue to focus on - and sincerely listen to - that person. People like to talk about themselves, so you can ask questions about where they work, what they like about where they are, why they came to the event, etc. If you are looking for specific information, you can weave that into your questions.
