Why is Kotlin compiling faster than Scala?

Question

When we read the wikipedia description of the Kotlin programming language, it states that:

JetBrains host Dmitry Dzhemerov said most languages ​​do not have the features they were looking for, with the exception of Scala. However, he called the slow compilation time of Scala an obvious flaw [4]. One of Kotlin's stated goals is to compile as fast as Java.

How did they achieve this goal? And why is Scala compilation time so slow that it was unacceptable to the creators of Kotlin? Or, in other words, what features of the Scala compiler make it slower than the Kotlin compiler?
