Key Topics Covered
Securitization Mechanics & SPV Structure
Covers the three-step securitization process from asset pooling through SPV transfer to bond issuance, the critical role of bankruptcy remoteness and true sale legal doctrine, and why the SPV allows securities to be rated based on collateral quality rather than originator creditworthiness.
Tranching, Waterfalls & Credit Enhancement
Explains the senior-mezzanine-equity layer structure with the payment waterfall and loss absorption from the bottom up, internal credit enhancement through subordination, overcollateralization, and excess spread, external credit enhancement via surety bonds, and the historical role and failure of monoline insurers.
MBS Analytics: Prepayment, Extension & Negative Convexity
Walks through prepayment risk when rates fall and extension risk when rates rise, creating the asymmetric payoff that defines MBS investing. Covers negative convexity where price appreciation is capped by borrower refinancing, and the counterintuitive negative duration of interest-only strips.
CLO Mechanics & Active Management
Explores how CLOs differ from static-pool ABS through active portfolio management, the reinvestment period that maintains leverage and enables par building, coverage test mechanics where IC test failures redirect cash from equity to senior note paydown, and the distinction between soft turbos and hard turbos.
Spread Analysis, Correlation & Synthetic Structures
Covers Z-spread versus OAS comparison for identifying relative value between bonds with different embedded options, SMM-to-CPR conversion using compounding formulas, default correlation effects that harm senior tranches but can benefit equity through binary payoffs, and synthetic securitization using CDS to transfer credit risk without asset transfer.
How to Prepare for Structured Finance Interviews
Be able to walk through a complete securitization structure from originator to SPV to tranched bonds, explaining why each component exists. Both sessions emphasize that understanding the motivation for securitization — capital relief, risk transfer, and funding cost advantage — is as important as knowing the mechanics.
Master the negative convexity concept for MBS and be able to explain why MBS trade at wider spreads than comparable corporate bonds. The advanced session shows interviewers expect you to articulate the asymmetric payoff: limited upside from prepayment when rates fall combined with full downside from extension when rates rise.
Practice the Z-spread versus OAS comparison with numerical examples. The advanced session presents a specific scenario where two bonds have identical Z-spreads of 150 basis points but different OAS values, and you must identify which offers better relative value by isolating pure credit spread from embedded option cost.
Understand the CLO reinvestment period and coverage test mechanics in detail. The advanced session demonstrates how an IC test failure diverts cash from equity to senior note paydown, and why the distinction between sequential pay, pro-rata pay, and turbo structures directly impacts investor returns across the capital structure.

200K+ students have used IB Vine to help land offers at top firms.
Analyst
The IB Vine technical prep is beyond helpful, it's so much more fun quizzing myself every now and then vs. reading through the guides again.
Analyst
I personally found that the 'IB Vine Select' collection had some of the exact questions I was asked in my Qatalyst interviews.
Analyst
Thanks for starting up IB Vine. Couldn't have landed my offer without your help!
User Story
I honestly think you're doing gods work since IB Vine democratizes the whole interview process and helps a lot of students ace their interviews.
Analyst
I found this website really helpful, which also helps me better prepare for the technical interview in IBD position and get an offer.

Check out IB Vine, specifically the 'IB Vine Select' questions. Once you can get a handle of those, it seems like you are in a spot where you're applying the concepts rather than simply memorizing them
Analyst
I've used IB Vine for my recruitment, and I could not imagine the journey without it. Thank you for creating a phenomenal resource.

Beyond the 400 questions guide, try to understand a deeper level and the underlying concepts of the questions being asked. Use ibvine, it really helps.

IB Vine has excellent questions, especially multistep ones. In my experience I've gotten grilled on accretion/dilution, bond math, and merger model questions. IB Vine has great practice for all of those.
User Story
As a nontraditional transfer student who has been rendered unavailable to many resources at my university (Leadership positions at clubs, immediately behind the recruiting cycle, etc.) IB Vine has been an absolute game changer in my IB prep.

From my experience interviewing FT for IB, it’s not enough to just know the 400 questions anymore (it’s a good starting point) but to look at even more advanced questions. Would recommend IB Vine.

heard all the new kids use IB Vine now. the questions on IB Vine helped me get the concepts down when I had to recruit and make a lot of BB/MM interviews easier than I expected for techs
User Story
Just got off the phone with a kid who interned at a Dallas PE firm. He mentioned that IB Vine helped him secure that internship as well as his Summer Analyst offer, especially since he came from a non-target with no resources.
