Lseg (london stock exchange group) Quantitative Analyst Interview Guide

Two candidates who interviewed for quant analyst roles at LSEG describe a process that starts with a conventional screen and then turns practical and market-focused. Only two reports cover this role, so treat the details below as examples, not a fixed format.

One candidate was told to expect a behavioral and fit interview followed by four rounds with managing directors. There, an interviewer asked them to discuss a current market event and explain how it would affect counterparty and credit risk. They found the link between market moves and exposure hard to articulate. Black-Scholes and call and put options also came up, with the emphasis on reasoning through pricing and trading dynamics, not reciting formulas.

The other candidate, interviewing for a junior quant role, described an HR screener, conversations with a country manager, and a final stage. That stage included a 30-minute technical test and meetings with the heads of Risk and Quant. Questions covered hedging autocallable options, pricing models for volatility products, and Value at Risk for mixed equity and options positions. They felt this went beyond entry-level depth.

In practice, prepare a recent market observation and rehearse tracing it to credit and counterparty risk. Be ready to talk through hedging and derivatives pricing out loud. Also have clear stories about your background and motivation, since both candidates faced behavioral questions early on.
