There are 5 interview stages at Wise:

1. Initial screening, a 30-minute talk to a recruiter.
2. Coding challenge, 60 min with two engineers. The task (45 min) was similar to LC 695 + implement input from stdin. Then 15 min for Q&A.
3. System design, 90 min with two engineers. Design Wise in simplified terms. I was asked about load balancing, idempotency, and consistency.
4. Product thinking interview, 60 min with a PM and prospective team lead, seems to be the hardest one :). Almost impossible to prepare yourself. I was asked questions about successful projects and measuring success, unsuccessful ones and possible reasons. Reading Wise's Medium blog helps here.
5. Final interview, 60 min with two engineers. Mix of questions about experience, mindset, preferred environment, etc. A variation of a cultural fit interview.

All in all, that was a quite nice experience. The recruiter sent me descriptions for each step as well as a blog post about the hiring process at Wise (dated 2018 but still relevant).
