IBvine is an investment banking interview prep platform that started as a student project. As of October 2026, its site describes 2,500+ curated questions, including more than 1,900 questions reported from real interviews across 50+ firms, 40 learning modules with flashcards and quizzes, 20+ hours of podcasts, a library of 90+ recorded mock interview sessions and 100+ case studies, many with an Excel model. It also sells packages to universities and student clubs. Its homepage does not list prices.
Breadth is IBvine's real advantage. A big bank of reported questions, sorted by firm, is a fast way to see the range of what interviewers ask, and the modules and podcasts help if you are still learning the concepts. If you have never seen an LBO question or a restructuring question before, reading a few hundred real ones is useful.
Reading a model answer and producing one are different skills. Interviewers do not ask whether you have seen the question; they ask it, wait, and follow up. Most candidates find they recognise far more answers than they can deliver cleanly out loud, and a question bank on its own cannot tell you which answers you would get wrong. That gap is what ApexIB is built around.

Use IBvine if you are early in recruiting and want to see as many real questions as possible, or you prefer learning from modules and podcasts.
Use ApexIB if you already know most of the material and want to find out what you would actually get wrong, practice saying answers out loud, and run full mock interviews and Superdays before the real thing.
The two also work together: read widely in a question bank, then practice delivering the answers in ApexIB. The free plan includes 5 graded answers a day and one full mock interview, so you can try it before paying.
