This isn't a bank of questions to memorize. Hardstop makes you build the answer, paper-LBO returns, EV-to-equity bridges, accretion/dilution, three-statement walks, typed out and graded live, the way a real interview actually tests you. 560+ original drills across comps, DCF, LBOs, M&A, accounting, credit and more, each with the full reasoning shown on every answer. Built for candidates breaking into investment banking and M&A: interviews, internships, and lateral transfers.
Difficulty isn't the role you're targeting. Analyst-job interviews routinely test Interview-ready and Mastery material, the Warm-up tier alone won't get you there.
The classic prep is to memorize a list of ~400 interview Q&As. You recognize the answer on the page, then freeze when an interviewer makes you derive it on the spot. Hardstop flips that: you produce the answer, every time.
No sign-up, no form. Thirty of the harder, interview-grade questions you actually work through, accounting, EV/equity and LBO math, adapting as you go. You'll get a read on your gaps at the end.
Each bar is your accuracy across that methodology. The tick marks the 70% proficiency line.
A read on your technical coverage, with a prioritized plan for your next session.
Specific questions you've missed, most recent and most repeated first.
Every question and explanation in Hardstop is independently authored, original work, with no text, figures, tables, or worked examples reproduced from any source. The platform is, however, built on the shoulders of the canonical works below: we studied them, synthesized their frameworks, and wrote our own drills to teach the same concepts. Several are not freely available, we credit them as the foundation of the discipline and encourage serious candidates to read the originals.
