In this episode we dig into the HackerRank annual survey that was released a few months ago for 2023 including the top in demand skills from employers in this uncertain tech and economic environment.

Note from Colin & CJ: This episode was recorded in November 2022. It is amazing how much changes in a few months.

Methodology for languages

To estimate employer demand for specific programming languages, we looked at HackerRank Work tests where a specific programming language was required, or where specific library questions were asked. Skill demand was estimated by the number of HackerRank Work tests using specific library questions.
On the preference – or supply–side, we tracked submitted languages by candidates when they have multiple options available, as well as their proficiency in those languages. We also included HankerRank Community practice data to get a full spectrum of skill preferences.
Notable these results are not survey results like the Stack Overflow survey
Demand for most languages growing, but not equally
