BlackRock - Associate data engineer interview - first interview

I have the first round of interview zoom call schedule with the manager not sure what needs to be prepared and it is for 1 hour for the position associate data engineer. I have prepared for data structures, sql, spark, data modeling and cloud but not sure what it's gonna be whether it is technical or non technical. Does anyone know who can guide me for the interview or any comments would be appreciated and it's for positions associate data engineer Georgia Atlanta. #blackrock #dataengineerinterview #dataengineer
