I was contacted by a staffing for DaoDao team and did an online assessment on codility. Two question: Algorithm and SQL. And follow up with a phone interview after a week. The phone interview only contains 1 problem, search how many squares in the graph. And if you haven't meet this problem before, you may know the answer. I tried hard and finally gave out a general solution which will take O(n^4) time complexity. The interviewer seems not listening when I'm trying to solve it. And they finally said they want to focus on senior role currently.

Interview process was fairly easy. A lot of behavioral questions with a small number of technical questions. Behavioral questions were fairly easy to answer. However your experience may be different. One on one interview over Zoom.
