I applied online. The process took 3 weeks. I interviewed at Uber (São Paulo, São Paulo) in Feb 2025
Interview
I participated in 3 stages from a total of 5. The first stage was a code challenge with 2 questions, focused on string and array. The second one was a chat with HR, focusing on my previous experiences and some simple technical open questions. The third was a pair programming challenge. The fourth and the fifth ones were supposed to be another pair programming challenge and then a system design.
