What Is OCI? A Complete Guide

What OCI Actually Is

OCI stands for On-Campus Interviews, although many programs now run virtually and use names such as EIP or EIW. It is a school-coordinated process in which employers interview students for summer or postgraduate roles. The format, eligible class years, selection rules, and calendar differ by school.

Think of it as speed dating for legal careers. You get about 20 minutes per interview. The firm decides if they want to see you again (a "callback"). You decide if you actually want to work there. Everyone's wearing suits and pretending to be relaxed.

OCI remains an important path into BigLaw, but it is no longer the only organizing channel. Firms also use direct applications, resume collections, early programs, referrals, and job fairs.

The timing has moved earlier and become less uniform. Yale publishes a January OCI program, NYU ran February 2026 EIW for the Class of 2028, and Harvard describes winter recruiting for the Class of 2028. Other schools and employers recruit on different schedules. If you are a 1L, use your own career office's class-specific calendar rather than a generic internet timeline.

Why OCI Matters So Much

School programs concentrate many employers and interviews into a short period, so missing your school's main window can reduce your options. It does not mean every firm has finished hiring: direct applications and later openings remain employer- and office-specific.

That doesn't mean it's your only shot, you can get BigLaw without OCI, but it's by far the widest door.

How the OCI Process Works

The process has several stages. Here's the sequence:

1. Bidding or applications

Some schools allocate interviews through student-ranked bids or a lottery; others allow employer prescreening or use a hybrid. Follow the rules and dates published for your program. Strategy matters here, so check out our OCI bidding guide for the details.

2. Screener interviews

These are the initial 20-minute interviews. The vast majority are now virtual, conducted over Zoom or a firm's preferred video platform. A handful of firms and schools still run in-person screeners on campus or at a nearby hotel, but virtual is the default. One interviewer, usually an associate or junior partner. The goal is simple: don't give them a reason to reject you, and give them at least one reason to remember you.

We break down exactly what to expect in our screener interview guide.

3. Callback interviews

If the firm likes what they see, you get a callback. Format varies. Some firms still fly you to the office for a half-day visit where you meet 3-5 attorneys plus a meal. Many firms have moved to fully virtual callbacks, and a growing share use a hybrid model: a virtual first round, an in-person second round for finalists. Either way, callbacks are where real decisions get made, on both sides.

Read more in our callback interview guide.

4. Offers

After callbacks, firms may extend offers for a later summer associate program. Timing and callback-to-offer rates vary by firm, office, practice demand, and year; do not plan around an unsourced universal percentage.

Who Participates in OCI?

Nearly every major BigLaw firm. We're talking about firms like Cravath, Kirkland & Ellis, Skadden, Wachtell, Sullivan & Cromwell, and roughly 100 others. You can browse the full firm directory to see which firms recruit at your school and what practice areas they emphasize.

Not every firm participates at every school, though. The biggest firms tend to recruit at T14 schools. As you move down the rankings, the number of participating firms drops. That's just reality.

What Firms Look for at OCI

Firms evaluate a few things during OCI:

• Grades. Your 1L GPA is the single biggest factor in getting screener interviews. Above the median at a T14 school? You'll have plenty of interviews. Below it? You'll need to be more strategic with your bids.
• Resume. Prior work experience, journal membership, moot court, interesting backgrounds, all of this matters.
• Personality. Can this person sit in a conference room with a client for 8 hours? Firms want people who are smart, curious, and not exhausting to be around.
• Interest in the firm. This is where research pays off. Knowing why you want this firm, specifically, is what separates you from the 40 other people they're interviewing that day. Use Big Law Bear's firm profiles to dig into practice strengths, culture, and compensation before you walk in.

How to Prepare for OCI

Preparation comes down to three things:

Know your story. Why law? Why BigLaw? Why this firm? You need clear, concise answers to all three. Practice them out loud until they sound natural, not rehearsed.

Research the firms. Don't just skim the website. Know their biggest recent deals, their standout practice areas, and something specific about why they interest you. Big Law Bear's firm directory has practice area breakdowns and key details for every top firm.

Prepare your questions. The questions you ask reveal more than the answers you give. Have 3-4 thoughtful questions ready for each firm. Our guide to common OCI interview questions covers both sides of the conversation.

Common OCI Mistakes

Students torpedo their chances in predictable ways. Applying too broadly. Not researching firms. Giving generic answers. Showing up in the wrong outfit. Forgetting to send thank-you emails (or sending bad ones).

We put together a list of the 7 biggest OCI mistakes so you can avoid them.

The Bottom Line

OCI is stressful, but it's also incredibly structured. That's actually good news, it means you can prepare for it systematically. Know the timeline, research the firms, practice your answers, and you'll be in strong shape.

If you're just starting to think about BigLaw recruiting, the best first step is to get familiar with the firms. Browse the firm directory, set up your Gold Stars to track your favorites, and start building your target list early.
