[@Adi300594]

Thanks for sharing

[@sumitmittal07]

Keep watching. More such interviews planned for all the data enthusiasts.

[@sandhyasandy9072]

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.
