Colloquio
Initial phone screen and then a 3 hour coding test, followed by another phone interview and an on-site interview. The initial phone screen was with one of their recruitment VPs. The coding test was pretty hard and I did it in Python. Then I had another phone interview with one of their quantitative analysts where we talked about ideas and then he asked 3 questions (1 probability, 1 statistics, 1 programming related). They invited me out for an in-person after this but I declined because I took another offer from another company.

Colloquio
Referred by a employer. Received an email to set up initial phone interview in a week or so. The first phone interview was basic questions about my research and some behavioral questions. The hiring manager was very polite and nice and he discussed about the internship role with me. At the end of the 20 mins interview, I was offered an opportunity to take an online coding test. They used HackRank website to setup the coding test (two problems in three hours). There are lots of coding exercises on HackRank you can practice in case you get a coding test offer. Make sure you can solve those at difficult level on HackRank. I did not pass the test and received a rejection email a week after.
