I was interviewed for Big Data engineer profile. Interview process took around 2 weeks.There was 1 telephonic discussion followed by 2 F2F technical rounds and 1 Managerial and HR round. Interview question's were mostly related to Hadoop ecosystem. However after 2 months i still did not get any confirmation from HR , Whenever i try to contact them, they says that they do not have confirmation from management or hiring team. I never expected such unprofessional behavior from company like Informatica.
