The interview process was in total a 4 hour process online. An hour of it was just a presentation with a group, where one person working there described Epic, what they do, the environment, etc. Then there was an hour where you were put with another TS engineer who you could ask questions for about an hour, and then you had the actual interview, which was all situational. My advice would be to express good time management as well as transparency with clients and coworkers, and you should be fine.
