iNextLabs interview questions

1st round asked about the basics. 2nd round the worst of all. He is being very rude and asking me why I am not knowing on that specific area they are working and he told that why not you not learned the questions asked in round 1. He is asking me to learn devops within a week because they asked me 1 round so that I should be ready in 2nd round with devops. Just blind questions who is in sales but taking technical interview.
