Pros
People do care about your growth and your wellbeing, including the more senior leadership - obviously, each partner/director are different and are willing to support to different extents. Performance is recognised internally, even if it doesn't directly translate into compensation. The culture encourages this too. Plenty of resources and learning opportunities, but if you have specific fields of learning you're interested in, you'll have to be self-driven and organised, as you won't get to do them during working hours (and this is the same in any company I would argue)
Cons
At times, to be a 'high-performer', you'll find yourself working long hours. Not the same as overseas big 4 or the MBB, but certainly more than what you are 'paid for'. Protecting work life balance therefore naturally comes at some compromise. New Zealand market is small. That means you won't always have industry or clientele continuity. You'll have to learn how to adapt very quickly and contextualise, which can be stressful when you're doing 8 projects in a year that are literally all from different markets. On the other hand, there are 'long projects' - these are less stimulating and repetitive throughout the project duration. Following on from above, it can mean that you aren't able to achieve 'depth' of skills that you might get with more specialised opportunities. The obvious flip-side is that you'd get a variety of exposures, so transferrable business knowledge and soft skills develop extremely quickly. To be fair, it's about what you want, so this isn't necessarily a 'con'.
