Hi there - I recently sat the first round and made it through ok. Essentially 2 parts:
- fit / situational meeting
- case study / fit
Be prepared to face some challenging situational questions esp around situations where you have faced challenges / obstacles and how you have resolved them. The case study is more likely to be based around market entry assessment rather than market sizing so familiarise yourself with key concepts. I didn't use a single framework nor a single word of management speak - refreshing to say the least!
