The process began with a phone call, we discussed basically details, reasons for wanting to join KnowBe4, reasons for wanting to leave my current employer.
The second interview came after I was recommended for a different position, so was really interview 1.1 which was very similar to interview 1.0.
The 3rd interview was with the team that I was interviewing to join, all participants had great questions regarding skills, knowledge of the field, etc., I got to ask all the questions I had, all around very informative.
The last interview was with a separate team I would directly be interacting with, a lot of similar questions to the 3rd interview, and again I got to ask a lot of questions and got answers.
