A couple of quizzes, you should be ready and already have some knowledge to take them. Make sure you have a goodnight's sleep and don't drink a lot of coffee so you can focus during the quizzes

I applied from their career site. Then automated mail received for 15 minute Reasoning assessment test (50 questions and 15min time). After completing Reasoning assessment, I received another email for Technical assessment (45 min for 28 questions). After completing Technical assessment, I received Real work challenge which required to record video and submit in 3 hours time. After completing all 3 steps, I received an email that due to high no of applications, my application is in backlog. Haven't received an update after this.
