Silicon Stack interview questions

I have given interview at Silicon Stack. Hr called me and asked about basics salary and location. After scheduled technical interview. Pictures comes in technical interview. interviewer seems to uneducated and unprofessional. he does not able to speak English properly started taking in hindi .He was more experience on paper but he is not able to explain question which he want to ask. 4 times he repeat but does not able to explain. Also I was feeling that when I was giving answer he started to talk like rude means how I am able to answer of his question. because he is more experience***

I received a call from HR regarding an interview opportunity. However, the interviewing team exhibited highly unprofessional behavior, speaking in Hindi and acting rudely. I would not recommend this company to anyone.
