Hi, I worked with S& for 3 years in London, including 6mo with the ME office (Dubai / Riyadh / Beirut) on several engagements, so I can offer you a few insights.
The important thing to understand is the culture of S& ME has always been quite differentiated as the earliest consulting firm to enter the market, they cultivate a distinct reputation as top-tier strategists from the Booz era. Like Clara pointed it, this culture has persisted even after the PwC acquisition, as a small-ish office in the network (one can say it's been distilled even further now). I can say time with the team in KSA highlighted this in how we worked, the team makeup (clear preference for quant majors e.g. engineering from AUB), and ruthless consistency in focussing on the details.
Why does this matter to you if interviewing?
Its high likely market sizing questions will come up, but the reason why is they want to test you can think like a strategist (note not a consultant, the point here is you don't need to know the content but can approach any problem through clarity of thought)
What would make you look like a start candidate to them would be:
- Clear ability to apply first-principles thinking
- Logical approaches to abstract concepts or questions
- Strong quantitative skills incl. mental maths
If I was in your shoes, my suggestion would be to spend time doing not just market sizing, but abstract estimation questions along with mental math.
Taking the above into account, really think through fit and how to demonstrate it. It is a particular brand of strategy consulting.
Let me know if you have any other questions.
