Nubank Mobile Developer interview questions

5 interviews and 1 technical challenge. You must wait a whole week for their feedback ON EACH STEP. At the end of all process and having wasted 5 weeks of my time, they said that they saw some gaps in my technical knowledge that were visible since the SECOND INTERVIEW! so, instead of stoping the process right away, they made me lose another 5 weeks of my time with nonsense.

I had a chat with an HR representative, they were looking for mobile engineers and I was interested. 2 weeks later the recruiter told me that they just want an engineer who wants to work in the backend, I rejected the opportunity because I didn't want that at that time.
