I applied through a recruiter. The process took 4 weeks. I interviewed at Nubank (Bogotá, Bogota) in Oct 2024
Interview
The interview process in total takes around 1 month. First interview is with HR where they check if you've got a cultural fit with the company. Next, you're given a challenge to be solved in a week. You can choose any programming language you feel comfortable with (I'd recommend you to always do that). Then you're going to do some pair programming with two senior engineers who will ask you to make some improvements to your code. You're supposed to collaborate with them as if you were coworkers. I'd suggest not always agreeing with them if you have reasons that support your design decisions, also ask for help if you feel stuck or would like to get some ideas. They won't help you solve the challenge, but they will definitely value that you ask questions. The final interview is with an engineering manager who is going to evaluate your career, accomplishments, etc. The process is very clear from day one and they give you tips for each stage of the process.
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.

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.
