How it works
The manual: what the placement test decides, every control on the practice screen, how to switch modes, and how the next question gets picked. The product on this page is live and the numbers are the real ones.
The placement test
The first thing the practice screen does for a new account: 5 questions, and nothing else on the screen changes. It looks like ordinary practice with a Placement stamp in the header.
- 01Everyone opens on Accounting. The same questions for everyone at each level, so no two candidates get a different test. The first three cards are multiple choice and the last is a flashcard, so you answer in both formats.
- 02Right steps up, wrong steps down. The five levels are Fundamentals, Accounting, Capital Structure, Valuation, and Deal Mechanics. A right answer moves the next question up a level and a miss moves it down. The first right answer jumps two.
- 03A level counts when you show it twice. One right pick on a four-option card is a 25% event, so a single guess never routes you past the foundation.
- 04The result decides where you start. Clear Valuation or higher and you go straight into GOBLINMODE. Anything less and you start the GOBLIN100 from question one, swiping past what you already know.
What it does to the map: every topic you answer right in the test lands at +0.50 instead of the usual +0.15, so two right answers on one topic close it outright. A miss costs the usual 0.15. Skip is at the end of the rail, and the map just starts empty.
The test has a page of its own, written for someone about to take it: the investment banking practice test.
The practice screen
One question at a time, with a thin bar of controls above it.

- The source. The firm and round the question was asked in, plus city and group where we have them. The bank's code opens it.
- The mode. Switches between the four modes. See Switching modes below.
- Where you are. Your position in the GOBLIN100 ramp. Tap it to open the outline and jump back to anything you have passed. In Bank & Round and Topics this slot names what you are drilling.
- Your map. Average score across every topic. Tap it to open the full map.
- Questions left today. 5 a day on the free plan, 80 on Accelerated — GOBLIN100 never counts against it. It turns red near the end.
The card
Four steps, every time. Reading an answer and saying it under a follow-up are different skills, and only one of them gets tested.
- 01See a real question. Tagged by firm, round, and topic.
- 02Answer it out loud. Say it the way you would in the room.
- 03Reveal the answer. All four sections at once.
- 04Mark it Know or Don't Know. That one tap is the only input the selection needs.
Equity value is $1,000 at a 25x P/E. Taxes are 20%, interest is $20, D&A is $30, and peers trade at 12x EBITDA. What is enterprise value?
The four answer sections
Every technical question carries all four. Each one exists because of a specific way candidates lose the room.
Switching modes
Four modes, one dropdown.
- GOBLIN100FreeThe first hundred questions in fixed order. Built for starting from zero.
- GOBLINMODEFreeRuns your prep for you: new topics as you earn them, misses brought back.
- Bank & RoundAcceleratedA set that mirrors one interview — a Goldman superday, an Evercore first round.
- TopicsAcceleratedOne weakness, drilled until it closes.
- 01Tap the mode label. The dropdown above the card. It always shows the current mode.
- 02Pick a mode. GOBLIN100 and GOBLINMODE start immediately. A gear icon means a setup panel opens first; an Accelerated badge means the mode is on the paid plan.
- 03Set it up and start. Bank & Round takes firms and rounds. Topics takes topics off your map. Both show the matching question count before you start.
No setup panel. This mode starts as soon as you pick it.
Your map
Every topic carries a score from 0 to 1. A right answer adds 0.15 and a miss takes the same 0.15 back, so a topic needs seven good answers to close and every miss costs you one of them.
- One topic at a time. GOBLINMODE works the first topic that has not reached 1 and weights it 100 against everything else. That is where most of your session lands.
- The rest trickles in. Later topics in the same section come through at weight 1, and get promoted to 5 once the topic in front of you passes 0.5.
- Finished means finished. A topic closes at 1 and nothing else counts as done. Break even at half your answers and it never closes.
How the next question gets picked
Every question you have seen carries a status, and the status sets how often it comes back. These are the real weights.
| Status | Weight | What it means |
|---|---|---|
| Never seen | 50 | New material outranks everything. Most of an early session is questions you have not met. |
| Don't Know | 20 | You missed it. It is twenty times likelier to come back than something you marked Know. |
| No answer | 5 | It was on screen and you walked away. It comes back more often than something you knew and less often than something you missed. |
| Know | 1 | You had it. It still turns up occasionally, which is how a Know that was a lucky guess gets caught. |
One tap per question is the whole input. Nothing to configure, no schedule to keep.
The GOBLIN100 syllabus
The whole ramp is public. 11 phases, 100 questions, fixed order, no weighting — question 37 comes after 36. Finish it and you land in GOBLINMODE, where anything you missed comes straight back.

Common questions
What is the OFFERGOBLIN placement test?+
A 5-question test, asked the first time a new account opens the practice screen. Everyone starts on Accounting; a right answer moves the next question up a level and a miss moves it down, across Fundamentals, Accounting, Capital Structure, Valuation, and Deal Mechanics. A level counts only when you clear it twice. Clear Valuation or higher and you start in GOBLINMODE; anything less starts the GOBLIN100 from question one. Every right answer in the test also lands on your map at +0.50 instead of the usual +0.15, so two right answers on one topic close it outright. You can skip it, but then your map starts empty.
How does OFFERGOBLIN decide which question to show next?+
Every question you have seen carries a status, and the status sets its weight in the draw: never seen is 50, Don't Know is 20, shown-but-unanswered is 5, and Know is 1. So a question you missed is twenty times likelier to come back than one you got right, and one you have never seen outranks both. GOBLIN100 is the exception: it plays a fixed order and ignores the weights entirely.
How do I change practice modes?+
Tap the mode label at the top of the practice screen — the uppercase dropdown in the center of the header. GOBLIN100 and GOBLINMODE start as soon as you pick them. Bank & Round opens a setup panel for firm and round, and Topics opens your map so you can stage specific topics; both of those come with Accelerated.
Is OFFERGOBLIN free?+
Yes, and no card is required. The free plan is the full GOBLIN100 with no daily limit, plus 5 GOBLINMODE questions a day. Accelerated ($39.99/month, or a $149.99 Season Pass that covers 12 months in one payment and does not renew) raises the daily limit to 80 and opens Bank & Round and Topics for people grinding a full recruiting cycle.
What are the four practice modes?+
GOBLIN100 runs the first hundred questions in fixed order, built for starting from zero. GOBLINMODE moves you through the curriculum on its own and brings back what you missed. Bank & Round builds a set matching a specific firm and interview stage. Topics drills one weakness until it closes. GOBLIN100 and GOBLINMODE are on the free plan.
What happens when I run out of questions for the day?+
The counter in the top right of the practice screen reads 0 left today, and the next pull opens the upgrade screen instead of a question. GOBLIN100 keeps going — the ramp never consumes the counter. Nothing is lost, and the count resets at midnight UTC. Free is 5 a day; Accelerated is 80.
Where do the questions come from?+
Real interviews at Wall Street firms, 1,000+ candidate interviews across 37 firms and recruiting cycles from 2015 to 2026. Every one is tagged by firm, round, and topic, and technical questions carry four sections: Direct Response, Intuition, Watch, and Deep Dive.
What does the map track?+
A score from 0 to 1 for every topic in the curriculum. A right answer adds 0.15 and a miss takes 0.15 back, so a topic needs seven good answers to reach 1 and every miss costs you one of them. GOBLINMODE works the first topic that has not closed yet and weights it 100 against everything else, while later topics in the same section trickle through at 1 and get promoted to 5 once the active topic passes 0.5.
Which firms are covered?+
Goldman Sachs, JPMorgan, Morgan Stanley, Evercore, Lazard, Bank of America, and 31 more bulge-bracket, elite-boutique, and middle-market firms. 26 of them have their own question page.
Do I need finance experience to start?+
No. GOBLIN100 runs 100 questions in fixed order from what an investment bank actually does to pitching a stock, so on day one you are not picking what to study. Questions across the rest of the bank run from beginner definitions to advanced valuation and modeling.
