The interview process was straight forward. I joined a call with one of their engineers. They use a software that allows you to edit the same document of code at the same time. They ask you some questions and work through with you.

I interviewed in Fall 2023. I met Ab Initio through a school career fair. It is required that you sign an NDA. There are two rounds: a technical screening round which is a standard coding interview question, as well as a final onsite, in which you talk to a plethora of people from across the company (think multiple developers, recruiters, etc.). Very pleasant experience, honestly. Everyone was extremely nice and very personable, and I had some great conversations with the team. The team is definitely very technical and expects you to be just as technical. I would recommend studying medium-level LC problems and just knowing your stuff.
