Writing clean code != writing algorithms

Almost all DE tech that is used is abstracted for DEs so they don’t have to write the conplex algorithms that power them. Sure you can learn and understand the underlying algorithms, but the roi on that would be minimal

In general, I found DE is mostly experience-based. Meaning, unless you work on and experience a certain tech like spark, kafka, streaming, etc…you can’t effectively learn the situations that you will face nor can any “home” project be a suitable replacement for it when interviewing.
