Full Interview Process Breakdown
Based on the accounts of multiple alumni, the BCG PTA interview process usually includes the following stages:
Stage 1: Online English Written Test
The written test runs about 15 to 20 minutes and mainly tests English writing ability. According to an interview account on the PTT Salary board:
Stage 1: an English written test, translating a Chinese news article into English. Source: PTT Salary board interview review
This stage tests not just your English level but, more importantly, whether you can convey information precisely in limited time.
Stage 2: Behavioral Interview + Fermi Estimation
The interview is usually a one-on-two or one-on-three format, covering:
- Self-introduction (in English)
- Questions on past experience (digging into your resume)
- Fermi estimation questions
One-on-two (or three?). 1. Self-introduction. 2. What did you do in your past summer internship? 3. If you had to estimate how many people see the fireworks at Taipei 101 on New Year's Eve, how would you estimate it? Source: PTT Salary board interview review
Another candidate shared a more detailed PTA interview structure on PTT:

Experiences from Those Who Have Been There
The Real Daily Life of a Consulting Internship
Someone who served as a summer intern at BCG's Taipei office shared that during the internship they handled a highly confidential project, working in a meeting room where even the windows were covered:
I learned a lot in the eight weeks of the internship and truly felt I was influencing Taiwan's future. Because I loved the internship experience so much, I joined BCG directly when I went full-time. Source: Sabina Huang interview, Chicago Booth MBA Johnny
BCG's Work Culture
Former BCG consultant Ivy Wu described the real work rhythm of consulting in an interview with CAREhER:
People at BCG have a scholarly streak. Under normal circumstances they are especially friendly, but once they get into discussing an actual issue, everyone shows their insistence on logic and truth. Source: CAREhER Podcast Ep.15, BCG Ivy Wu
Ivy also stressed that a successful consultant needs three key abilities: stress resilience, calm in the face of uncertainty, and the ability to build and maintain networks. She specifically mentioned needing to "control the density of communication logically," which is precisely the most core ability in a consultant's daily work.
Non-Business-School Backgrounds Have a Chance Too
According to one interview account found in our research, a second-year computer science student at National Taiwan University, despite having no relevant consulting experience and rating their own interview performance as average, still successfully landed a BCG PTA offer. This shows BCG values thinking potential over an existing background.
Key Interview Reminders
In a PTT interview account, one candidate specifically mentioned their own mistake:
I did not clarify which part of the industry the client wanted to invest in. Source: PTT Salary board consulting interview experience
This is a reminder to everyone preparing for interviews: when answering case questions, always clarify the scope of the problem first and do not rush into analysis.
Who Is This Job For
You May Be a Great Fit If You...
- Have a natural curiosity about business problems: you proactively wonder "why is this convenience store's location better than the one next door?"
- Enjoy breaking down complex problems: you can structure a vague, big problem into smaller, analyzable pieces
- Have balanced and strong Chinese and English ability: a PTA needs to switch seamlessly between Chinese and English daily, and the written test directly tests translation
- Can maintain output quality under high pressure: every consulting task has tight time pressure and requires fast delivery of high-quality results
- Are interested in many different industries: BCG projects span finance, technology, consumer goods, and more
- Are good at teamwork and communication: you need to collaborate closely with senior consultants and clearly express your analytical logic
You May Not Be a Great Fit If You...
- Prefer a stable, predictable work rhythm: consulting moves fast and is full of uncertainty, with project content and timelines changing often
- Are not good at quickly learning new fields under pressure: each project may involve a completely different industry, requiring you to become "half an expert" in a short time
- Expect to be taught step by step: BCG's culture emphasizes initiative, and even interns are expected to complete research tasks independently
- Cannot steadily commit 18 to 20 hours per week: a PTA requires a long-term, stable time commitment, which can be hard to balance during a demanding semester
