Epic interview questions

I was contacted by HR on LinkedIn. There was a general info session on Zoom after which we were scheduled for an massive interview session. It wasn't necessarily group interviews, but I was in my seat from 10:00am to 4:00pm with various sessions such as info or QA or scenario-based questions to final one-on-one with HR. It was a long process with only a 15min break. It seemed a little excessive for an interview.

The interview begins with an initial phone screen, then behavioral profile and logic exam, and ends with a multi-round group interview. The logic exam is notoriously confusing and the coding section is pretty tough (especially for those with minimal coding experience).
