Hi sir, please do an interview video on gcp data engineer
Definitely, will be planning for it in the upcoming weeks
This is really good for beginners.
this series is gold
Glad to know that you are finding the series valuable!
Sir please make the interviews more complex to know more questions as every time we are listening the same questions. Like salting technics, bucketing,unity catalog, auto loader,z order clustering in databricks. spark joins other than broadcast ,concepts of data skew,spilling,OOM issues etc.. Also we face so many questions related to data modelling like fact and dimension tables star and snowflake schema. Different file format questions and methods (explode,flatten)we use to load the data.
hello Sandhya, this upcoming week we will conduct bar raiser rounds. you can expect higher difficulty level.
@@sumitmittal07 Thank you Sir 🙏
Please do an interview on snowflake as well
sure, noted.
This is a nice series, but missing followup questions from the interviewer.
Its great that you are enjoying the series. I will definitely ensure that some follow-up questions will be covered by the interviewer in the upcoming videos.
Thanks for sharing
Keep watching. More such interviews planned for all the data enthusiasts.
Would the interview would be this easy?
depends on interviewer and our luck
