1 assessment and 1 interview session. Assessment is on overall testing process both manual and automated (very details!), and there is so many questions. Asked to do in 2 hours but I did take time about 3.5 hours. Interview is with 2 person, maybe the QA lead/manager. They mainly asked about my Katalon Studio experience and that is all but they do ask many question on how I do testing using Katalon.
