Pros
The culture is what makes TransferWise. Great people who truly believe in the mission and a team that's enabled to execute with very few barriers (what we call autonomous teams). The business's ambition + the ability to impact give a strong sense of empowerment and the engagement levels are unmatched. Your career at TransferWise is truly what you make of it, the culture and structure within the business enable this to an extent that I have not seen elsewhere.
Cons
It can be overwhelming and chaotic at times, but what do you expect from a (very) fast growing business? There's a lack of process in some areas and your impact can be determined by your ability to understand how things get done within this environment. However this also gives a lot of flexibility/autonomy once you've figured this out.
