They have three rounds.
First: Phone screen, a recruiter will contact you and ask you some introduction question. Then some question about OOP, SQL, and some behaviour questions.
Second round: Online assessment.This includes two parts: Technical and Behaviour. In technical, you will do a MCQ test about OOP, Java,SQL, and problem solving questions. In the behaviour part, you will film a video answering some questions.
Third round: First you will have to listen to a presentation about FDM. Then they will move you to a one-on-one technical interview, the questions in this one is easy, no coding, just asking almost the same with the phone screen round. Then move on to a behaviour part, same like other interviews that you can search on Google; they will ask what do you know about FDM as well so do some research.
