Hadoop & Spark Course

I recently interviewed at Apple and was pretty satisfied with my performance except for the fact that I couldn't answer any of the Hadoop/Spark related questions. I just said I haven't worked with it professionally yet and only know stuff on the surface level. I rarely see it as a requirement for DA/DS roles but still decided to fill this knowledge gap.

Does anyone know of any good hands-on Hadoop/Spark courses, preferably available on LinkedIn learning? One of the questions I received revolved around using broadcast joins, so it should be quite practical.
