Interview
fter the HR interview, there is a coding interview. They pay attention to every little detail. Even though I wrote the code correctly, I was rejected because I asked questions. It’s quite an unusual process where they expect senior candidates to complete everything without asking any questions.

I applied through a recruiter. I interviewed at Wise (Londres, Inglaterra) in Nov 2025
Interview
pairing interview was real good and the people I met there was perfect, The system design interview was very amateur and unprofessional. asking about customer experiences to gather the requirements and you may end up being redirected the same question to you (the question was should the experience be immediate synronous or async with notification is acceptable here), when I heard that I wanted to say depends... but I swallowed it. so unmature.

I applied online. I interviewed at Wise (Londres, Inglaterra) in Oct 2025
Interview
The interview process began with an initial screening, leading to a pair programming round with two engineers. I successfully completed the core coding task, but some of the test cases were not satisfied. Regrettably, my candidacy did not proceed to the subsequent interview stage.

Question 1
We have a web client that makes requests to Service B and Service C.
If either service fails 3 times within 10 minutes, we should stop making requests to that service for 5 minutes (circuit breaker open). After 5 minutes, we should try again (circuit breaker half-open/closed). We need to implement this logic in the `WebClient.execute(Request)` method.
