Collaboration is central to your day-to-day work.

Q: Is the technical test always the same for every Consultant role? No. The technical assessment is tailored to the specific needs of the department. It may range from a logic and numerical test to a take-home project or a system demo.

Q: What is the best way to prepare for the case study/role-play? Focus on your structure. Interviewers are less interested in a "perfect" answer and more interested in how you logically approach a problem under constraints. Practice communicating your steps clearly as you go.

Q: What if I don't have experience with a specific tool mentioned in the job description? Be honest about your experience, but highlight your ability to learn quickly. LSEG (London Stock Exchange Group) values potential and the capacity to adapt to new technologies.
