Business casual. Very kind interviewer, be prepared for an aptitude test. The first interview was very casual, they have very open ended questions letting you take the floor, so be prepared to get vauge questions!

I applied online and received an email with a link to a personality & logic test. After completing the test I got a request to do a video interview with the recruiter so I could retake the assessment while sharing my screen to ensure it was me answering the questions. After completing the assessment the recruiter outlined the position and the next steps in the interview process. Then I answered a couple of basic questions and asked a couple of questions about the company and that was it! I did not make it to the next round of interviews.
