Direct answer

OFFERGOBLIN is a cards-based investment banking interview prep platform with over 3,500 verified Wall Street interview questions across 37 firms. Candidates practice in four main modes (GOBLINMODE, GOBLIN100, Bank & Round, and Topics), and every technical question carries four sections: Direct Response, Intuition, Trap, and Deep Dive. The free plan, Casual, gives GOBLIN100 unlimited plus 5 GOBLINMODE questions a day. Accelerated is $39.99 a month, or $149.99 for a 12-month Season Pass, with 80 GOBLINMODE questions a day, voice practice, and the bank, round, and topic filters.

The product loop

Open the app. Read the question. Answer it: pick an option, answer it on a flashcard, or say it out loud. Check the full answer. Mark it Know This or Don't Know. Move to the next card.

That is the loop. The platform is built around it. Everything else (the article library and the recruiting guides) exists to support that core practice cycle.

The loop is built around retrieval, not recognition. Reading a textbook teaches a candidate to recognize a DCF when they see one. The OFFERGOBLIN loop teaches a candidate to produce the DCF answer cleanly when an interviewer asks for it.
