Pros: Didn't find any.

Cons:

1. Very time consuming.
2. Wait for feedback for at least 2 weeks after each round.
3. Unprofessional and rude interviewer.
4. Process doesn't make sense at all.
5. After every round, the recruiter will call and mention that you fall in the lower range of the salary because of the feedback.

Process:

1. Recruiter's call (15 mins).
2. Pair programming (same currency conversion question, mentioned in other reviews) (60 mins).
3. System design (your current project design and one system design problem) (90 mins).
4. Product round (60 mins). Some PM will interview you. Mine was very rude and had limited knowledge about the payment system, just knew a few things he was working on, which explains why he was rude and unprofessional.
5. Hiring manager round (with two interviewers) (60 mins). These people will tell you that you don't know your project which you are working on and they know it better. This round told me a lot about the company culture and the toxic environment.

My advice to the recruiter and interviewers at Wise is: You have all the right to reject candidates based on your parameters, but being rude and condescending to applicants just because you can is not right. It shows your personality and impacts the company's reputation as well.

Coding: currency conversion API design.

System design: One payment service.

Product round: A few sensible questions about your current project and a lot of stupid questions to prove that they know something.

Final round: This round is just to prove that you know nothing, and no matter how much you prepare, they know your project better than you.

Note: Recruiters are also very unprofessional as they don't take notes. I had to remind her that we had already discussed a few topics and could skip them.
