Nubank CodeSignal assessment


May 17, 2026
The coding task was to design a banking system in CodeSignal. It was divided into 4 sections. The complexity increases with each section.

First Section(with certain constraints): CreateAccount, DepositMoney, TransferMoney (to another account)

Second Section: Top n accounts with highest outgoing transactions.

Third Section: Schedule payments and transactions.

Fourth Section: Couldn't get till here as was out of time.

The Goal is to pass all the unit tests for a certain section and only then you can move forward to the next section.

没米 请问是哪家银行？

不是lz，但只有可能是NuBank

这家应该在湾区扩张，最近在密集招聘…面试第一轮就是sys design，直接跳过刷题面
