First round: Met with managers from multiple teams and a tech lead. Asked both behavioral and technical questions. Very friendly and laid back group.
Second Round: A live coding interview with a few leetcode (easy) questions alongside trivia checking your knowledge of the language(s). Overall, a very fair assessment. An example of one question is: given a list of prices, find the highest, then apply a discount, then return new overall total price of all items. A low stress and supportive interview. Make sure you communicate well!
Third Round: Meet with Director of IT. Nice guy, I went in expecting it to be purely a "get to know me", it was, but it was also still an interview, so treat it as such.
Fourth Round: Didn't make it this far, but apparently you're to meet with someone above the Director of IT.
