Unproctored, timed, custom HackerRank followed by a technical interview with 3 members of the engineering staff led by your would-be lead.
The HackerRank is one "question", not leetcode, just revolves around making API calls and saving responses given some arbitrary business rules. I would equate to somewhere between a Leetcode Easy or Leetcode Medium problem.
The technical interview began with a design problem you would either type or draw through and have a two-way conversation with the Automatiq engineers about handling X Y Z, DB choices, et al. This takes around an hour, after which they ask questions around your experience with web scraping, unit testing, and a couple smaller topics. They really seem to want someone familiar with Selenium or a related browser-automation tool.
