I went for a interview got selected after 2 weeks of waiting traning started that was also OK the main issue was on time of certification when I was on call with client the trainer didn't let me complete my call and after that I was not feeling well so I left from. There as doctor suggested I was not present for two days when I contacted the trainer she told me that I was fumbling and grammar was not correct in only first call how can she assume that she hasn't allow to take certification again as I requested her she told to talk to HR when I tried to connect to HR she told to contact trainer they both were pushing on each other no result
So I suggest Canadiates not to join opening which ever eureka outsource is providing
Bcoz the process they are having is hopeless
I wasted my time and money nearly a month
