The short version
Wall Street Prep's Premium Package is $499 for seven courses and roughly 46 hours of core content: Financial Statement Modeling, DCF, M&A, Trading Comps, Transaction Comps, LBO, plus a bonus module. Finish the exams and you are eligible for their Financial and Valuation Modeling Certification. It is a real curriculum, taught properly, and it is the industry standard for a reason.
Wall Street Prep also sells the Red Book, a $99 PDF of 1,000 interview questions and answers. That one does the same job as OFFERGOBLIN, so it gets its own section below.
OFFERGOBLIN is $39.99 a month, or free at 5 questions a day. It holds 3,500+ interview questions candidates reported after real rounds, tagged by firm, round, topic and difficulty, each with a structured written answer.
One teaches you to build a model in Excel. The other decides whether you can answer "walk me through an LBO" in ninety seconds without stalling. Those are different skills and the interview only tests the second one.

What is Wall Street Prep?
Wall Street Prep is one of the two names everyone in this category knows. The Premium Package is the flagship: seven self-paced courses covering financial statement modeling, DCF, M&A, trading comps, transaction comps and LBO, built around video lessons, Excel templates and real filings. Around 46 hours of core content, plus more than 25 bonus mini-courses and a month of PitchBook.
Their courses are used in bank training programs, which is the strongest credential a prep product in this space can have.
What it does well
- The modeling instruction is the real thing. Step-by-step, built on actual filings, taught by people who did the job. If you cannot build a three-statement model, this fixes that.
- The certification carries weight. It is a line on a resume that recruiters recognize, which almost nothing else in this category offers.
- Bank-adopted. Used inside training programs at firms, which is a level of validation no startup in this space has.
- One payment. $499 once, not a subscription running in the background.
- Breadth of technique. Trading comps and transaction comps get full courses, not a chapter.
What the Premium Package does not offer
- Interview questions. Wall Street Prep sells those separately, in the Red Book (below).
- Questions attributed to specific firms and rounds.
- Behavioral prep. That is the Blue Book, also sold separately.
- A free tier or published trial.
- Anything that adapts to what you personally keep getting wrong.
- A published refund policy on the package page.
What is OFFERGOBLIN?
OFFERGOBLIN does one thing: flashcards for investment banking interviews, built to be the best in the world at that and nothing else.
The bank. 3,500+ active questions, technical and behavioral, at 37 firms, synced from the live database on every deploy. Every question began as a first-hand report from someone who sat the interview, out of 1,000+ reports across 12 recruiting cycles going back to 2015. Each is checked, stripped of identifying details, merged when it duplicates something already there, and tagged with the firm, round, topic and difficulty. All of it is readable before you pay.
The engine. GOBLINMODE weights every question before it picks, using how you rated each one and where you sit in the curriculum. The topics you dodge are the ones you see the most. Anything you marked "don't know" keeps coming back until it stops being a miss. You never build a study plan.
The answers. Four sections on every answer: Direct Response, the answer itself. Intuition, why it is right. Trap, the wrong answer sitting inside it. And a Deep Dive into the mechanics underneath.
The ramp. GOBLIN100 is 100 questions in fixed order across 11 phases, teaching each concept before a question depends on it. Free, and it does not touch the daily counter.
Built by someone who did it. Attended UChicago for an MBA and an MS in Computer Science, was technical lead for the banking club, worked at Centerview, then built OFFERGOBLIN. On Leland he holds both coach badges, Top Expert and Customer Favorite, rated 5.0, coaching investment banking recruiting at $250 an hour. He runs the Instagram and TikTok himself and answers messages.
The limits, plainly: no modeling course, no Excel instruction, no certification, no mock interviews, no resume review, no mobile app.
Different jobs, and how to tell which one you need
The useful question is not which product is better. It is which gap you actually have.
You need Wall Street Prep if you cannot build the model. If a three-statement model is a mystery, if you have never linked a debt schedule, if "circularity" is a word you nod at rather than understand, no amount of flashcards fixes that. Sit down with the curriculum and do the work.
You need OFFERGOBLIN if you understand the concepts but freeze when asked. This is more common than people admit. You know what a DCF is. You have built one. Then somebody asks you to walk through it out loud in ninety seconds and you start in the wrong place, ramble through WACC, and lose them. That gap is a drilling problem, not a knowledge problem, and it is what the flashcards are for.
Most people recruiting seriously have both gaps, in that order. Learn to build it, then drill saying it. At $499 plus a free tier, or $499 plus $39.99 a month during the weeks that matter, that is not an expensive stack.
Where the two genuinely overlap is technical coverage. Wall Street Prep teaches LBO mechanics across nearly ten hours. OFFERGOBLIN holds the LBO questions candidates were actually asked at 37 named firms, with the answer and the script. Deep instruction against tested recall. If you only have money for one, pick based on which of those you are short of.
The Red Book vs OFFERGOBLIN
The Red Book is Wall Street Prep's interview guide: 1,000 questions and answers in a PDF, with links to companion videos when a concept needs more than a paragraph.
What the Red Book does well
- It goes wide. Past accounting, valuation, M&A and LBO, it carries 243 capital markets questions and 380 industry questions across tech, media and SaaS, FIG and restructuring. For FIG or a media group, that section goes deeper than our bank does.
- $99, once. Less than three months of OFFERGOBLIN.
- You can read a sample first. The product page links a free sample PDF.
Where a book runs out
A page prints the answer under the question, so you read it before you have tried to say it. A card holds the answer back until you have answered.
The Red Book opens with accounting. GOBLIN100 opens with what a bank does, what a stock is and what a bond is, and reaches the three statements at question 17.
A book does not know what you missed. Finish GOBLIN100 and GOBLINMODE starts at the first topic you have not cleared, with every card you marked "don't know" back in the deck.
On accounting, valuation, M&A and LBO, the Red Book has 390 questions and names no firm or round. GOBLINMODE covers those four plus capital structure with 2,300+, and almost every one names the firm that asked it.
The order we would use
Start with GOBLIN100. It is free and it covers the core in order. Then drill in GOBLINMODE until the misses stop. Our bank has sector questions too, which you drill by tag. If you are interviewing into FIG or a media group and want more, the Red Book's industry section is worth the $99.

Which one should you use?
This is not a budget question. It is a sequencing question.
Wall Street Prep if you cannot build the model. Flashcards do not teach modeling and drilling will not substitute for the curriculum. Go and do the work.
OFFERGOBLIN if you can build it and still freeze when asked about it. That is a rehearsal problem, not a knowledge problem, and rehearsal is what the interview actually tests.
The Red Book or OFFERGOBLIN for the questions themselves? Run GOBLIN100 first. It costs nothing, and by question 100 you will know whether you want a book to read as well.
Most serious candidates have both gaps, in that order. Learn it, then drill saying it. $499 once plus a permanent free tier covers both, and neither purchase is the expensive part of recruiting.
Is Wall Street Prep worth it in 2026?
For what it is, yes. $499 for a bank-adopted modeling curriculum with a recognized certification is a fair price, and the instruction quality is not in question. The thing to be clear-eyed about is what it does not do: it will not tell you what Evercore asked in a first round last cycle, and it will not drill you until your answers are automatic. Those are separate problems and you should know which one is yours before you spend anything.
What is the best Wall Street Prep alternative?
For modeling instruction specifically, Breaking Into Wall Street is the direct alternative at a similar price, with a 90-day unconditional money-back guarantee that Wall Street Prep does not publish.
For interview drilling rather than modeling instruction, OFFERGOBLIN is the alternative, and the free tier does not expire, so checking it costs nothing.
