NEC Corporation Sr Software Engineer interview questions

Very Bad, the attitude of the interviewer is very bad. It was for .Net core GraphQL Fullstack with Angular. Firstly the interview is for 30 mins which is very less to judge a person with particular experience. No introduction of himself and not even bothered about what I know. Straight away asking questions about graphQL. Since I am a beginner in GraphQL ,but still insisted that I know all the concepts in that. Next he moved to Angular, Here the moment I answered he is interrupting all my answer. Next topic was Microservice no time give each and every time he interrupt. It feels like he is taking the interview just to fail you, and he makes you feel you know nothing by passing side comments. It was not professional by him. I felt like just leaving the interview. After all that he ended by asking the same graphQL question giving complicated scenario even after telling that I dont know much about it. It seems NEC are hiring some ignorant people to interview. Be very careful before joining here, if developers are like this I dont know how management is.
