There were around 7 rounds in total, including the "work trial" at the end-4 days where you work for the company for less than minimum wage as a full time employee. The first 5 rounds were a couple of HR interviews and some basic SQL and Excel questions, pretty easy. The 6th round was a very light in-person behavioral/skill round. The job is essentially using Looker ML to create visualizations for them, with very limited SQL and Excel; not a lot of opportunity to build skills in more popular softwares. The hours are long (around 12 a day), and while the employees are lovely, management is crabby and expects a high output from you from Day 1 with 0 training. I dropped out midway through the work trial--while there are plenty of companies I'd be willing to put in long hours for, Zealthy unfortunately was not one of them.
