He asked me about complete functionality of Maven though I am not a maven expert and no where I have mentioned that in my resume. Looks like they were looking for Maven expert rather then the whole DevOps expert. Also asked me theoretical questions like what are the best practices to write a Dockerfile. I never googled it. In my 10 years of experience client never asked me about that. He gave me the work. I delivered it with the best of its quality. He was super satisfied. Job done. But this man Gopal was so keen to make the final decision based on thesee irrelevant questions.
