A sample answer to question 1

What does a principal consultant do that a senior consultant or manager does not, and why do you want that step?

A principal consultant is a recognised expert and trusted adviser. A senior consultant delivers well, and a manager runs delivery, but a principal shapes what we sell and how we solve problems. I would expect to lead the intellectual content of engagements, advise the client's senior leadership, mentor managers and contribute to proposals and thought leadership. I would also carry a share of the sales pipeline and relationships, as well as a utilisation target. I want that step because I have reached the point where my greatest contribution is in framing problems and developing others rather than managing every workstream. My own work has increasingly involved advising directors and helping win follow-on work, and I enjoy the combination of depth in my specialism with building client relationships over years rather than months.

Common mistake to avoid: Describing it as a bigger delivery role; ignoring sales expectations
