Terra Quantum interview questions

Friendly conversation to get to know each other at first interview. Then an average-difficulty task for approximately 1 week and a second interview to present your solution when you're ready.

The invitation to the first interview took about 3 weeks. The first step was then an interview of about half an hour to get to know each other. The second step then was a Data Science challenge which I had 1 week to solve, with a subsequent presentation. The challenge was a lot of work such that it was bad to never hear back from the company afterwards. Even after checking back they did not reply.
