Eximius Design ASIC Verification Engineer interview questions

Eximius might have most un professional HR team in industry. My first telephonic round of interview was rescheduled thrice without any prior intimation by HR, they schedule a day and time for it but no call from penal even HR people were also un traceable at that time then HR called me after couple of days to reschedule it.. This happens 3 times and finally I got a call from technical penal.. Then they insist me to take second round on same day, I go for it but no further communication after that. May be for them my interview was not up to that level but that's different thing..
