Belzabar Software Design Computer Scientist interview questions

One of HR contacted me and asked me to attempt one Online coding exercise, I have cleared this round and she arranged Skype F2F round. Skype F2F round interview was pathetic in other words worst interview experience I have ever had. It started with introducing myself and this led to one problem solving and Core java, Lamda expression, Spring Boot discussion later on. I have answered few of them and few of them I have clearly said I don't have idea. I was very genuine about by interview and adhered all professionalism during interview Process. But, There were two interviewers who were taking my interview , one of them was young age computer scientist working in Belzabar was extremely professional. But, other guy who was in full of attitude and sitting quite in beginning and once he started speaking he doesn't know how to speak well English and then also he was pointing me without looking my profile background. He was just randomly asking technical questions which he doesn't even have any idea about. In that case, he should at least adhere professionalism and follow some interview etiquette but he did't do any of these. In interview process after asking questions he used to laugh on me that was truly unprofessional. I would request to CEO or CTO or HR department of company to arrange any professional course so that he can follow some etiquette. At last I have asked about company when they have given chance me to ask if I have any questions. In reply, he said you have not gone to our company website then you are not interested and anyway we are also a software company develop software and sell it to service based company with laugh again. He din't bother to explain about company and it's key working area. Delhi NCR company's employee review is already not good so, keep that in mind and try to adhere professionalism. You are not the boss of company You are also an employee so behave like employee of IT company. Don't behave like any mafia or don. I request to CTO and CEO of this company to take action against it and arrange some program for such employees to follow some etiquette and adhere professionalism.

The process started with an online coding testing which comprised of 2 coding questions. Then i was asked to come for face to face interviews. I had two technical interviews on the same day with difficulty level varying from easy to moderate. After that i had the HR round.
