JetBrains Software Engineer interview questions

Primero tenias q entregar un ejerció que enviaban a todo el mundo, era responder como resolverías un problema contando con un conjunto de datos. Después de esto, si eras elegido, pasabas a la siguiente ronda, era una ronda final, si la pasabas te hacían una oferta.

I applied for the internship I had a challenging task which I managed to tackle. The interview was delayed till last day of the deadline, after me sending them a follow up email about my internship application status they offered me an interview mentioning the tried to do this before but the couldn't because of some internal issues. The interviewers introduced them and the company and how things work with the internship, Though I wrote the code more than 1 months ago because of the delay from their side, I remembered almost everything and answered all the questions. After the interview I got rejection and I asked for feedback and unfortunately I haven't got Any. A disappointing experience for the effort I put in such a task and the whole process.
