1. He asked what all programming languages you know other than front-end? I said recently I have worked on Python and previously worked on Java (6 years back).
The guy only knew Java and kept on asking questions related to Java. The question were however very simple and college graduate level.
2. He asked whether you have worked Database design & implementation? I said I know MySQL, Oracle SQL then he asked do you know NoSQL. I said no and he kept on asking questions related NoSQL.
Such a stupid and unprofessional person.
Despite declining multiple times and requesting to focus interview on front-end skills, he kept asking NoSQL related questions.
3. Then he asked about Elastic Search and told how does it work? My answer was generic and being in front-end development I never worked on its implementation. He still kept asking questions related to it.
