Interest Rate Models: Quant Interview Playbook
The ultimate quantitative finance interview guide for aspiring rates traders, quants, and risk managers. This comprehensive playbook demystifies the models actually used on trading desks—Hull-White, LMM, and SABR—by bridging theory with practical PnL and hedging intuition.
What You'll Master:
Module 1: Yield curve dynamics (level, slope, curvature) and DV01 decomposition
Module 2: Why naive models fail (LTCM, 2008 crisis, SNB case studies)
Module 3: Short-rate models (Vasicek, CIR, Hull-White 1F/2F) with Greeks
Module 4: HJM framework and Musiela parameterization
Module 5: LMM calibration, drift cascade, and correlation matrices
Module 6: SABR smile models for negative rates environments
Module 7: PnL attribution and model reserve methodology
Module 8: 20+ classic interview questions with model answers
Key Features:
8 cheat sheets (60-second summaries per module)
10+ practical diagrams (Colab-ready generation scripts included)
Model selection decision trees and product mapping
Historical case studies (LTCM, LIBOR transition)
Calibration algorithms and parameter stability checks
Model risk vs market risk frameworks
"What interviewers are really testing" analysis boxes
Who This Is For:
Rates Quants: Daily model calibration with PnL language
Derivatives Traders: Swaption, Bermudan, and exotic pricing
Risk/XVA Quants: CVA, PFE, and capital model drivers
Interview Candidates: 48-hour crash course with decision trees
Prerequisites: Black-Scholes intuition, basic fixed income (swaps/FRAs), stochastic calculus (SDEs/Itô), DV01/Gamma/Vega. No measure theory or heavy PDEs required—focus is on modeling logic, not proofs.
Includes:
One-page essential formulas cheat sheet
Model DNA cards (tear-out reference)
Python diagram generation scripts for Colab
Mock interview simulation (35 minutes)
Final checklist self-test
Format: PDF document with vector diagrams, cross-referenced tables, and searchable text. Optimized for dual-screen use: left screen for model, right screen for hedging during risk meetings.
