I applied online. The process took three months.

I applied for a position on Nubank's website. The interviewing process consisted of one screening interview, a chat with an engineer, a take-away task of building an application in Clojure, a chat with the hiring committee, and finally an on-site interview in Sao Paulo. The last stage of the interview involved a pair-programming session, an architecture interview, and a conversation with the product owner. Despite not getting an offer, my overall experience was very positive.

Learn basic Clojure and build a simple application.
