1 - Call with hr and team leads talking about big data experience with spark hadoop etc 2- Onsite 1 hour with leads talking about big data architecture experience, projects worked on 3 - 1 hour technical with quick fire questions and usual leetcode nonsense 4 - 1 hour with hiring manager have examples ready of the usual difficult times I done this etc. Was able to answer about 75-80% of quick fire questions although no offer. Just play the game and revise the definitions and you should be fine. I dont know what asking someone do they remember this definition proves anything, suppose its better than a take home coding test. If hr told me its a definition interview I would have revised the definitions before going in.
