Eka Software Solutions interview questions

I went for the interview for java profile on 14th May 2019 in Embassy Tech Village Bellandur Bangalore. I reach office late over there because of Traffic issues on Peak Hours in Morning time. Even I already Inform to the panel team that I will reach office little bit late. When I reach to the office one HR came and Asked my name. Start Abusing me. How u came late your Interview is suppose to be this time. You doesn't have any manners u should come on time for interview. That guy literally Insulted me in front of everyone and abused me and he told me that u can leave the company right away. My question is that is this the way you treat with the Experience candidates by abuse them and insult them in front everyone. Whether they treating us we are just slave for this company. If their employees behavior is like this during Interview time then what will happen if I will join their EkaSoftwareSolutions company then they will treat us badly like them slave. But I am really disappointed from employees behavior it is unprofessional manner.
