Ninety Nine Financial Markets interview questions

First call with CTO and CIO to present the company and the position, then an exercise to do at home without time, and finally a technical interview to defend the solution. After this whole process, I never had any feedback on the process, and I don't know if they think candidates' time is free, but if you made them spend time in a process, at least give them feedback.

There was an initial call with a recruiter, a cultural fit with the CTO and a code test with no time limit to do an API. The API had to be either in JAVA or Kotlin, and in my opinion wasn't a code to complete enterely, but to left some comments where you explain what to do with the remaining parts.
