Firstly i was asked to implement a task using Angular and Nodejs and host it on cloud.I cleared that then i was asked to attend a face to face round.There they asked me about the projects on which I have worked upon.It was of 40 mints.At the end i contacted HR and she told me that they are not hiring for Node developer.So i asked her then why you invited me for the interview.Very unprofessional HR.They don't value the time of other. Advice to HR shortlist candidates as per your requirement.
