The Professional Career Guide: What Consulting, Banking, Private Equity, and Tech Internships Are Actually Like

By Rosie & Co. Global — rosiecoglobal.com In collaboration with ECZ Management Partners, Perpetua, and Ciao AI

Why We Built This Guide

Choosing a career path can feel overwhelming, especially when the most competitive opportunities require students to prepare early, build relationships intentionally, and navigate recruiting processes that are rarely explained clearly in the classroom.

So we put together the Professional Career Guide — a look inside four of the most sought-after early-career paths: consulting, investment banking, private equity, and technology. Rather than telling students which path is "right," the goal is to show what the work actually looks like day to day, what internships demand, and how to position yourself for each opportunity.

The throughline across every conversation we had while building this guide: the strongest candidates aren't the ones with every step mapped out from day one. They're the ones who stay curious, take initiative, seek out people with firsthand experience, and turn each internship, project, and conversation into a clearer sense of where they can contribute.

Building Momentum Before You Have a Plan

We opened the guide with a conversation with Jiayi Xu, a Penn student whose path has spanned private equity, marketing, and social impact work. Her story reflects something increasingly true across every industry: a degree alone isn't enough anymore. Students are expected to build experience, relationships, and clarity early — often before they know exactly what they want to do.

A few things stood out from her approach:

• She optimized for learning, not prestige. Early internships were a way to test different environments, not to chase the most impressive name.
• Community did more than any single strategy. Being around people who were applying, sharing leads, and pushing each other forward created momentum that's hard to replicate alone.
• A simple system beat a perfect one. A calendar, career-services support, and consistent follow-through carried her further than any elaborate process.
• She took unpaid and "unimpressive" opportunities early, treating access and exposure as more valuable than prestige in the short term.

Her advice to students still figuring out their path: talk to early professionals, take small opportunities even if they feel like a waste of time, and let clarity build from there.

Inside Consulting: BCG and Bain

Consulting is one of the most pursued — and least understood — career paths on campus. We spoke with consultants at both Boston Consulting Group and Bain & Company to get past the "every day is different" cliché and into the actual rhythm of the work.

What the day-to-day looks like: Projects start with a kickoff, move into structuring the problem into workstreams, then shift into deep analytical work — research, data, and slide-building aimed at a clear takeaway, not just a chart. Hypothesis-driven problem solving keeps teams from chasing analysis that doesn't move the answer forward, and the pace intensifies as findings get synthesized for client leadership.

What surprised people most: Not the hours, but the culture. One BCG consultant expected a sink-or-swim environment and instead found genuine mentorship — though the learning curve stayed steep regardless. At Bain, the surprise was realizing how much less "answer cracking" happens early on; junior team members are usually building the evidence behind a direction, not discovering it from scratch.

What helped candidates stand out: Case practice that produced sharper, less generic answers; case competition experience that mirrored real consulting work; and, in a few cases, an unconventional academic background that gave interviewers something to remember.

Inside Investment Banking

We talked to a Penn alum in banking and a rising analyst who completed her sophomore summer internship to understand what the job actually demands beyond the reputation.

The work: Financial modeling, pitchbook creation and revision, and company or industry research — most of it iterative, detail-heavy, and directly tied to live client decisions. Hours regularly run 70 to 100 per week during active deals, and the schedule is reactive by nature: priorities can shift the moment a client calls.

What surprised them most: Less the workload itself and more its relentlessness — everything feels important at once, and small mistakes ripple into extra work for the whole team. One theme came up again and again: banking can feel like "school after school," where the relationships built under pressure end up being just as valuable as the technical skills.

What it takes to break in: Networking to secure the first conversation, technical fluency in financial statements, valuation, and deal mechanics, and — just as important — the ability to explain your background clearly under pressure. Consistency mattered more than any single "perfect" interaction; the candidates who navigated recruiting best were the ones who stayed organized and kept preparing even when the process felt opaque.

Inside Private Equity

Private equity has a quieter, more selective reputation than banking or consulting — which can make it feel more polished from the outside than it actually is. We spoke with a Penn alumnus who transitioned into PE after four years in consulting, along with a student who completed a PE internship.

The work: Less "making the call" and more building the case for it. Junior team members spend most of their time in financial models, data rooms, and industry research, then synthesize it all into investment memos that inform a senior team's decision. Because PE teams are small, junior work feeds directly into real capital decisions — responsibility arrives earlier than most students expect.

What surprised them: How much of the job is Excel, document review, and refining assumptions rather than big strategic calls — and how much less standardized the recruiting process is compared to banking. Most PE opportunities, especially at smaller firms, are never posted publicly at all.

What helped candidates stand out: Thinking like an investor rather than just executing tasks — identifying risk, understanding the business model, and forming a real point of view. A consulting background translated well for some, and persistent, relationship-driven networking mattered more here than almost anywhere else in finance.

Inside Tech

To round out the guide, we spoke with a software engineer at Microsoft and a Penn student who completed a software engineering internship, since tech recruiting looks and feels different from finance and consulting.

The work: Less about building something new every day and more about maintaining, debugging, and improving systems already in production — investigating incidents, fixing bugs, writing tests, and getting comfortable navigating a large, unfamiliar codebase before touching it.

What surprised them most: How much of the job is reading code and communicating, not writing code in isolation. Debugging and documentation took up more time than either expected, and the lack of tightly defined goals meant success depended more on self-direction than constant oversight.

What helped candidates stand out: Strong fundamentals in data structures and algorithms, real projects that demonstrated initiative, and — especially for candidates with a non-engineering background — the ability to explain their thinking clearly while solving a problem, not just arrive at the right answer.

A Founder's Perspective: Jacqueline Deprey on Building Perpetua

The guide closes with a piece from Jacqueline Deprey, Co-Founder and CEO of Perpetua, on what building a company has taught her about entrepreneurship. Her framework for anyone considering the founder path:

1. Start with a problem you're genuinely passionate about solving — you'll spend far more time with it than you expect, and progress won't always match the effort you put in.
2. Solve problems you're uniquely qualified to solve. Earned insights — knowledge built from direct experience with a problem — are what separate a founder's bet on themselves from just a bet on an idea.
3. Understand what people are actually willing to pay for, not just what they say they care about.

Her own path from privacy and data work at Apple and Dropbox to building Perpetua is a reminder that the most durable company ideas often come from something deeply personal, combined with a skill set earned the hard way.
