Presto Data Engineer interview questions

Totally 6 Rounds - 5 technical and 1 VP round. Asked about Bigdata , Pyspark architecture, aws Glue. Mostly from resume. Second round was crucial - project manager round- Writing SQL queries from basic to intermediate. 3rd 4th 5th round - asked from resume and end to end project (which you worked), explain about exciting work which you worked on. 6th- same like above- Technical and project explanation. At the end he said he will check with second round guy- such a waste of time, unnecessarily given interview with 4 different rounds and persons .
