How OFFERGOBLIN works
How it works
OFFERGOBLIN is flashcards for the investment banking interview. See a real question, reveal the full breakdown, and mark what you know — the engine keeps resurfacing your misses until they are reflexes.
One card — a real interview question, and the full structured answer when you reveal it.
The drill
It's a flashcard drill
One card at a time, the same loop every time — until the answer is automatic.
See a real question
Pulled from the bank, tagged by firm, round, and topic.
Answer it out loud
Say it the way you would across the desk in the interview.
Reveal the breakdown
Check yourself against the full structured answer.
Mark what you know
Know or Don't Know — the engine resurfaces every miss.
MODES
Choose how you drill
GOBLINMODE reads your history and keeps serving the questions you keep missing. Switch to GOBLIN100 for the core ramp every candidate should know cold, or pick Bank & Round and Topics to target exactly what you need.
ANSWERS
Every answer, broken down
No wall of text. Each question comes back in the same stacked structure, so you know exactly what to say — and how far the interviewer can push it.
Direct response
The answer you lead with — tight enough to say out loud in the room.
Intuition
Why it is true, so you hold up when the interviewer pushes on it.
Watch
The traps and follow-ups interviewers use to see how deep you really go.
Deep dive
The full mechanics — tables, walkthroughs, worked numbers — when you want more.
BY FIRM
Rehearse for the firm on your calendar
Filter by bank and interview round — a Goldman superday, an Evercore first round, a Morgan Stanley screen. Every question came from a real interview at that firm.
