The interview process having first round of interview on Skype, which for me has been taken by a Full Stack Developer for a kubernetes administrator which is totally a different skill sets. After that they will send you an assignments on mail which after completing I came to know that the way (gitHub and DockerHub) through which I have shared an assignment is not the correct one, I don't know if there any better way then Github and docker hub to share the images, containers and helm-charts. Anyways this is what will happen so make sure before getting the assignments to ask them clearly how they want an answer may be they were expecting a word or a pdf file.
