Colloquio
I applied online at the end of October and got a Hackerrank challenge invitation the next day. Overall, the process was very quick.
Hackerrank challenge for 48 hours + a phone interview with an HR + an onsite with 3 interviews:
1. Intro/Programming Interview - Discussing the Hackerrank challenge.
2. Computer Science Fundamentals - I expected the usual algorithms questions but it turned out to be about how computer hardware/software works, networking, and everything around it. I feel like my knowledge of these was quite poor but I used general logic to answer the questions.
3. Project Deep Dive - Discussing one of your recent projects.
During the onsite, I had time to ask questions about the company at the end of each interview and I got lunch with two new grads.
