Honorable Mention
Arthur D Little is not a new name. Founded in 1886, it prides itself as the world's first management consulting firm. ADL - a global management consultancy specializing in strategy and operations management serving major corporations and organizations worldwide - has offices in over 20 countries. The firm is known to link strategy, innovation, and technology together.
The London office is very inviting and friendly - it is not too big, which allows you to get to know your colleagues (and you are not just a number at a desk like at some Big 4 firms). For interns and junior staff, you get wide exposure to experts, seniors, and partners. The culture is informal and very flexible, as long as your work gets done.
The projects you get to work on are interesting; the Telecom practice is very popular in London. Management has a very entrepreneurial mindset and encourages your ideas and zeal to pursue new opportunities. In the London office, you get a lot of diverse and interesting cases. In fact, Business Analysts present to a CEO one week and then might get to work on a separate case for an IPO the next week.
The people at Arthur D Little are engaging and come from very diverse backgrounds - they are not your usual firm, where 98% of staff with Business and MBA degrees (good news if you're trying to take a non-traditional path). If you tend to work smart rather than boiling the ocean, you will notice a significant opportunity to pursue work-life balance at Arthur D Little London. The hours are long, but better than in most top tier firms.
The pay in London is good but certainly not as good compared to top tier consulting firms. Because ADL is lean, strong integrated support systems don't exist like they would at McKinsey or Strategy&. Therefore, your team will have to do your own "deep analysis."
