I interviewed at Wise Estonia. The first round was with the HR recruiter. The recruiter was very nice and explained the whole interview process very well.

The second round was a pair programming session with two software engineers (from London. Beware of the interviewers from London as mentioned in every other Wise review).

Pair programming round:

The question was like currency conversion. I had two methods where one was sending money and the other was receiving money. I had to refactor the code based on edge cases like sending should happen if the receiver is there and has an account, and all other relevant edge cases. I had the perfect solution ready to implement the current conversion using BFS, which the interviewer asked for first. But while I was implementing the solution, the interviewers stopped me and redirected me to the money transfer part.

We handled the currency conversion part via a dummy API, and then we had a lot of back-and-forth discussions and code implementation/changes on the money transfer part. I addressed all the edge cases and follow-up questions well, and the interview overall felt like it went well. Nowhere did the interviewer nudge me that I was doing something wrong, so the result I got from the technical interview was very unexpected for me, considering I completed everything accordingly.

There was no feedback as to why I got rejected, so I would say it was overall a negative experience interviewing with the Wise team. They should definitely learn how to conduct an interview and should be upfront about the passing criteria. They should also work on their pair programming part of the interview.

Refactor money transfer methods based on edge cases and also implement currency conversion.
