I applied online. The process took 4 weeks. I interviewed at Nubank (São Paulo, ) in Aug 2020
Interview
Step 1: A talk with a tech recruiter
Step 2: Take-home assignment
Step 3: Architectural discussion "whiteboard"
I did not pass the whiteboard step
During the whiteboard step I was supposed to have 1 hour to solve a given solution, but I had only 40 minutes as the interviewer arrived late, besides she was quite rude while making questions and did not give any feedback.
I was confident because my solution was quite similar to the Nubank's solution.
I do not think my interviewer is ready to be part of a hiring process, which is quite unfortunate as I really had a good time working on the take-home assignment and talking to the tech recruiter.
Codesignal round with some DSA / OOP is the first pre screening, Each question is in increasing difficulty, there are 4 questions. It is important to manage time as there is just 90 minutes to complete the task, ran out of time and was not able to even start the 4th problem.

Question 1
Multi level OOP style coding question in increasing difficulty
I applied through a recruiter. I interviewed at Nubank in Apr 2026
Interview
The interview process took around 2 months. I was provided with comprehensive steps before each round that was very helpful during the process. However, I felt the overall duration of interview process was time-consuming.
First round was an online coding round, second was a system design and third was pair programming. The expectations were very contradictory - you are required to execute independently in a pair programming round and still get rejected for not pair programming and executing independently.
They wouldn't give you enough time to think and keep asking you to think out loud. Some people like to think before saying their idea out loud thus the instructions and expectations don't align well.
O meu processo contou com envio de currículo, teste de lógica que pode ser feito em qualquer linguagem, envio de teste mobile também em qualquer linguagem, pair programming que foi basicamente explicar o meu código e aplicar extensões e uma última entrevista sobre experiencias passadas.
