Eternal vs 10X EBITDA
PE interview prep vs. PE deal execution.
10X EBITDA offers PE-focused interview prep and technical guides.
“"Technical PE interview prep that actually works."”
10X EBITDA is well-regarded for PE technicals. But PE interviews test your ability to explain deals. Eternal tests your ability to do them.
A deal is not a spreadsheet.
A deal is a transaction. It starts when you first open the CIM and ends when you’re sitting across from a seller at closing. In between, you’re evaluating a business you’ve never run, making judgments about a management team you’ve met twice, negotiating terms with a counterparty who has more information than you, and defending your thesis in front of partners paid to find holes in it.
None of that lives in a spreadsheet. The model is the last hour. Eternal is built around the other forty.

10X EBITDA prepares you for the interview. Eternal prepares you for the decade after it.
10X EBITDA does a solid job on PE technicals and interview preparation. If you have a live PE interview next week, their guides are worth reviewing. But once you're in the seat, the interview questions stop and the actual deal work begins. Eternal picks up exactly where interview prep ends: real transaction scenarios, cascading consequences, and IC-level judgment that no technical guide can teach you.
