About the role
Consultant role overview
A Consultant in the UK works across McKinsey, Boston Consulting Group, Bain and similar organisations, using tools like Salesforce, Confluence, Jira, PowerPoint, Excel on a daily basis. The role sits within the professional services & consulting sector and involves a mix of technical work, stakeholder communication, and problem-solving. It's a career that rewards both deep specialist knowledge and the ability to collaborate across teams.
Most UK consultants either enter straight from university (via graduate schemes) or transition from associate roles (2–3 years post-university). Some transition client-side from corporate roles after 5+ years experience. Consulting values analytical thinking, communication, and client impact over deep technical expertise.
Day to day, consultants are expected to manage competing priorities, stay current with industry developments, and deliver measurable results. The role has grown significantly in recent years as demand for professional services & consulting professionals continues to rise across the UK job market.

Before you interview
Interview tips for Consultant
Consultant interviews in the UK typically involve a mix of competency questions and practical exercises. Come prepared with measurable outcomes and concrete project examples that demonstrate your capability — vague answers about "teamwork" or "problem-solving" won't cut it. Be ready to discuss your experience with Salesforce, Confluence, Jira — interviewers will probe how you've applied these in practice, not just whether you've heard of them.
Research the organisation's professional services & consulting approach before you walk in. Understand their recent projects, market position, and what challenges they're likely facing. The strongest candidates connect their experience directly to the employer's priorities rather than reciting a rehearsed pitch.
For behavioural questions, structure your answers around a specific situation, what you did, and the measurable outcome. Be specific about numbers, timelines, and outcomes — "increased efficiency by 22% over six months" lands better than "improved the process."

Baseline skills
Qualifications for Consultant
Most UK consultants either enter straight from university (via graduate schemes) or transition from associate roles (2–3 years post-university). Some transition client-side from corporate roles after 5+ years experience. Consulting values analytical thinking, communication, and client impact over deep technical expertise. Relevant certifications include None mandatory; PMP, ITIL, or domain certifications valued depending on specialism. Employers increasingly value practical experience alongside formal qualifications, so internships, placements, and portfolio work can be just as important as academic credentials.
Preparation tactics
How to answer well
Use the STAR method
Structure every behavioural answer with Situation, Task, Action, Result. Interviewers want narrative, not bullet points.
Be specific with numbers
Replace vague claims with measurable impact. Not "improved efficiency" — say "reduced processing time from 8 hours to 2 hours".
Research the company
Know their recent news, products, and challenges. Reference them naturally when answering. Shows genuine interest.
Prepare your questions
Interviewers always ask "what questions do you have?" Show you've done homework. Ask about team dynamics, success metrics, or company direction.
Technical competencies
Essential skills for Consultant roles
These are the core competencies interviewers will probe. Prepare examples that demonstrate each one.
Frequently asked questions
What's the difference between a consultant and a senior consultant?
Consultants typically own a project workstream and manage junior staff (3–5 years experience post-university). Senior consultants lead entire engagements, own client relationships, and have broader commercial responsibility (7–10 years experience). Consultants report to senior consultants/partners; senior consultants report to partners.
What percentage of time are consultants on client sites versus in the office?
Varies by project and firm. Some consultants are 100% client-based; others cycle between 80% client, 20% office (proposals, training, internal work). Average is probably 60–80% client-facing. Expect significant travel. Some firms are shifting towards hybrid/remote models.
How realistic is the partnership track at a consulting firm?
Depends on firm and individual. Some consultants make partner within 10–15 years; others take 20+. Not everyone is partnership material or interested. Many consultants transition client-side at manager or director level rather than pursue partner track. Partnership requires business development success alongside delivery excellence.
What happens if you don't progress to senior consultant on schedule?
Most consultancies have defined progression timelines (e.g., 3 years to senior consultant). If you don't progress, you're typically encouraged to find a new role (client-side transition, move to another firm, or exit the profession). Some firms are creating alternative tracks (non-partnership senior roles) for high performers who don't want the partner grind.
How much client-facing work versus internal work is typical for a consultant?
As a consultant, expect 70–80% billable (client-facing) work and 20–30% unbillable (proposals, training, internal projects). Utilisation targets are typically 70–75% annually. Time not billable is often on business development or training. Some firms are more flexible if you're strong at new business.
What's the realistic salary progression from consultant to partner?
Consultant £42–52k base, ~£45–60k with bonus. Senior Consultant £65–85k base, ~£75–100k with bonus. Manager £95–130k+ base, ~£120–180k with bonus and profit share. Partners at large firms can earn £250k–1m+ depending on firm performance and personal book of business. Progression is gradual but material jumps occur at senior consultant and partner levels.
