Great Parallelism, Partition Overhead
A partition is a chunk of data that is processed independently by Spark workers.
The number of partitions typically affects performance. More partitions allow better parallelism, but too many small partitions can add overhead.
Good partitioning leads to faster, more distributed processing.

Completed a coding test and three rounds of interviews. Contacted via a third party. The interview went well. The last management round panel said I was a good fit. Then they ghosted and did not give an offer. A waste of time.
