I could not agree more.

In many technical interviews, they want to talk about "scalability", using fancy big data software for horizontal scalability etc

But I also know from experience that many, many of these problems would be more elegantly solved by more traditional tools like Postgres, especially since servers have gotten more powerful, the cloud service options more plentiful and reliable, and the software more optimized. The "scalable" approach can lead to massive amounts of wasted person hours unless you're sure you really need it. But if you say, "just use RDS or CloudSQL, or maybe BigQuery", you get perceived as a newb by the 24 year old who just got his MS doing Spark work on toy problems.
