There is a online test comprising 4 MCQs and 3 coding questions, time limit is 2 hours. After that, a phone interview by one of their software engineers, the quality of the phone connection is not that good, I could not even hear some of the questions clearly, don't get so depressed from that, I believe it is the same for other applicants. Then comes the assessment center, there are three face-to-face interviews with their software engineer on the area of algorithm, behavioral and software engineering technical interview. My advice: practice leetcode easy/medium level questions, you should be able to do most of algorithm questions.
