Hi guys!
I think both your approaches are great and similar to what I often did. I also don't see any harm in honing into a specific practice area, especially if this is one of the firm's key areas.
I would often structure my answer using the pointers below.
- The firm's work e.g. interesting/landmark deals, specific industries, clients etc.
- The training structure e.g. seat structure ( how many seat rotations, chances for international or client secondments, firm's approach to work)
- The firm's culture (this will of course depend on the level of interaction you have had with the firm or if you have a specific area of interest regarding the firms culture e.g. D&I initiatives)
For each I would focus on 1 or 2 key things then expand in detail and relate back to me and my experiences.
