1 Kayak Online Interview, questions are some common ones online, not hard. 4 rounds, splited into 2 days considering my time difference. 1 OOD, 1 Coding, 1 System Design, 1 Behavior Questions. All are easy, just some common problems online, added some details. Not hard, interviewers are nice, and arrangement is good. The platform to draw is not easy to use, remember to practice before the interviews.
