Applied online through their website. I got a request for solving a timed HackerRank quiz. Unfortunately, I had not heeded the descriptions on this website. You need to prepare well for the HackerRank test. The UI for Hackerrank is horrible, be sure to be try it out first and practice. I wasnt prepared and failed to finish the tests on time. If i were do this again, I would practice a couple months on HackerRank. Its a different way to test and I was not used to it.

I had a couple of interviews with senior guys, the questions were use case ones with technical questions. I passed them both, but did not like 2 things: first was that interviews were usually scheduled with little anticipation and no detail of what it would be about, second the guys in charge of the interviews didn't seemed interested in the interview nor they spoke good english.

They give use cases and later on questions regarding it, similar to traditional McKinsey, but with a more technical focus.

Oniline coding test which I passed, and then online tech interview (using Zoom app) which I failed.
Coding test questions look easy at the first glance but once coding them, they were not straighforward and require some thoughts. So you need to manage time.
Tech interview was led by two data scientists over a video chat. First part was for case study. The interviewer gave me a brief introduction to a project and let me share how to tackle it. Second part was for ML knowledge check.
I thought I gave reasonable answers but failed. The HR contact gave me a call after the interview and share the feedback which is good. However, the feedback itself didn't make much sense.
Interviewers were junior to me (that is, shorter years of education and industry career) and the questions seemed to be
designed for junior/entry level candidates.
