Avantages
1 - Really interesting colleagues. 2 - Really interesting clients. 3 - Really interesting work. 4 - Great, fun workplace culture (So so so so much better than other places I've worked) inc.: climbing; frisbee; lunch chat together every day; parties; other nonsense. 5 - Freedom to do basically anything you want with your role so long as it's good for the company. 6 - Self-managed workload (good if you need a light week). 7 - Very flexible hours/days. 8 - Didn't furlough or fire any consultants during Covid. 9 - Management are impressively open to criticism (like, you-can-pull-the-CEO-into-a-room-and-pick-holes-in-their-decisions type open) and will re-write policy that is not working (or is shown to be non-inclusive, or discriminatory, or whatever).
Inconvénients
A - Pay is good, but no Deloitte. B - Self-managed workload (bad if you are junior and/or susceptible to inviting overwork) C - With hands-off management (and without commissions or bonuses), self-motivation can be difficult. D - As with all consultancy, the uncertainty can be stressful. E - Frustratingly risk/cost-averse facilities management, but that's a very minor thing. The office is more exciting than it used to be. Thankfully.
