Before You Walk Into That Career Fair, Choose Your Prep Strategy

Most people think event prep means printing 50 résumés and rehearsing a 30-second pitch until it sounds like a voicemail greeting. That’s wrong. The real work happens before you ever set foot in the room: choosing who you’re going to talk to and what you’re going to ask. At career fairs and industry mixers, the students and early-career folks who walk away with interviews aren’t the ones with the slickest pitch—they’re the ones who prepared for a conversation, not a performance.

We’ve seen this play out repeatedly. At a recent university career fair, one student spent the first 20 minutes memorizing her elevator pitch in the hallway. Another student had already looked up five companies and identified two alumni from his school. Guess who got the follow-up interview? The second one. His preparation wasn’t about self-promotion; it was about creating a genuine connection.

So when we prep for an event, we’re really deciding between three strategies: the Informational Interview Prep, the Elevator Conversation Prep, and the Weak-Tie Activation Prep. Each has its place, but they’re not equally effective for every situation. Below, we break down how they compare on four criteria: goal clarity, research burden, conversion potential, and follow-through. Then we’ll tell you which one wins—and when.

Option 1: Informational Interview Prep

This is the gold standard for events where you have time to schedule one-on-one conversations. An informational interview is an informal chat, usually 20–30 minutes, with someone working in a field that interests you. It’s not a job interview, and you’re not asking for a job. Instead, you’re gathering information about their career path, the organization, and the industry. The prep work is substantial: you research the person, their company, and the field; you prepare open-ended questions; and you reach out by email or LinkedIn, making it clear you want information, not a job (UC Berkeley Career Engagement).

This strategy shines when you’re exploring a career direction or trying to get an inside look at a specific organization. It’s also the most reliable way to build a relationship that can later lead to referrals. But it requires a longer runway—you can’t just show up at a career fair and expect an informational interview on the spot. You need to plan weeks in advance.

Option 2: Elevator Conversation Prep

Elevator conversations are the bread and butter of career fairs and networking mixers. The idea is to have a concise self-introduction that highlights your background, interests, and what you’re looking for. But here’s the nuance: an elevator conversation should be organic. Instead of pitching why you’re the best, you listen for real opportunities to form a connection (University at Buffalo Career Design Studio). The prep involves crafting a few key elements: identify yourself, mention your goals or skills, establish a connection by referencing something the other person said, and ask for a follow-up action like a further conversation or a message.

This strategy is ideal for high-volume events where you’ll talk to many people in a short time. It’s low-commitment and flexible. But it can also be shallow if you don’t do your homework. Without research on the companies and people attending, your elevator conversation becomes generic, and you’ll blend into the crowd.

Option 3: Weak-Tie Activation Prep

This is the most underrated strategy, and it’s backed by decades of research. The “strength of weak ties” concept, first introduced by sociologist Mark Granovetter in 1973, shows that acquaintances—not close friends—are more likely to lead you to new opportunities because they bridge different social circles (NIH OITE (Granovetter)). A 2022 study in Science using 20 million LinkedIn users found that moderately weak ties, with roughly 10 mutual connections, were the most helpful for job mobility (MIT Sloan (weak ties study)).

So how do you prep for an event using weak ties? Before the event, you scan the attendee list or LinkedIn event page for people who are not in your immediate circle but share a mutual connection or a common interest. You then prepare a short, personalized message to send before the event or a conversational opener to use in person. The goal is to activate those dormant connections. This strategy requires the most upfront research and social courage, but it can yield the highest returns, especially in fast-moving industries like tech or R&D where weak ties are particularly valuable (HBS Working Knowledge (weak ties study)).

Head-to-Head: Which Prep Wins?

We compared the three strategies on four criteria that matter most for event preparation. Here’s how they stack up:

If you’re attending a career fair with dozens of employers and you have limited time, Elevator Conversation Prep is the minimum viable strategy. It gets you in the door and lets you practice. But if you want to maximize your chances of converting conversations into interviews, Weak-Tie Activation Prep is the winner. It combines the research rigor of informational interviewing with the event-floor practicality of elevator conversations. And the data backs it up: students who engaged in cold networking—reaching out to people without a preexisting relationship—were twice as likely to earn an internship as those who only used warm networking (UVA Economics (NACE cold networking study)).

That said, weak-tie activation isn’t for everyone. If you’re early in your exploration and don’t yet know what you want, informational interviews are a better fit. They let you learn without the pressure of asking for anything. And if you’re an introvert who dreads walking up to strangers, elevator conversation prep gives you a script to fall back on. The key is to match the strategy to your goal and your comfort level.

How to Execute Each Strategy

Here’s a quick guide to putting these strategies into action:

• For Informational Interview Prep: Identify 3–5 people you admire in your target field. Send a personalized LinkedIn message asking for 20 minutes of their time to learn about their career path. Prepare 5–7 open-ended questions. After the chat, send a thank-you note within 1–2 days and offer to return the favor (UC Berkeley Career Engagement).
• For Elevator Conversation Prep: Draft a 30-second introduction that includes who you are, what you’re looking for, and a question for the other person. Practice it out loud, but keep it flexible. At the event, listen more than you talk. Ask for a follow-up action, like connecting on LinkedIn or a brief call.
• For Weak-Tie Activation Prep: Before the event, scan the attendee list for people who share a mutual connection or a common interest. Send a brief message: “I noticed we’re both connected to [Name] and will be at [Event]. I’d love to say hello and hear about your work in [Field].” At the event, seek them out and have a genuine conversation. Follow up within 24 hours.

One more thing: don’t neglect the basics. LinkedIn reports that members with a profile photo receive 21x more profile views and up to 9x more connection requests than those without one (LinkedIn Job Search Guide (official)). So before any event, make sure your LinkedIn profile is polished. It’s the digital handshake that often precedes the in-person one.

Bottom Line

If you’re preparing for a career fair or networking event, the single best move is to spend 30 minutes researching who will be there and identifying two or three weak ties you can activate. That means finding people who aren’t in your inner circle but share a connection or interest. Reach out before the event, have a real conversation, and follow up within a day. This approach combines the relationship-building power of informational interviews with the efficiency of elevator conversations—and it’s backed by research showing that weak ties are the hidden engine of job mobility. Skip the generic pitch. Do the homework. Talk to the right people.
