Obviously a typo, they probably meant 1-2 years, which is realistic. While this is probably not actually the case here, I see it quite often that companies have unrealistic expectations when it comes to work experience with technologies like k8s. For example it is quite common here in Berlin to expect 4+ years of k8s experience. Which is unrealistic to find taking into account that k8s initial release was 6 years ago. It is paradox that companies want to use the latest technologies and require years of work experience at the same time.
