HCLTech Quality Control - ISO 13485 Domain interview questions

I received a call letter from Technojobz and i came to know that its a directly recruitment for HCL (not through any other consultancy payroll) So i was happy to attend the interview in HCL (AMB-4) Chennai on Oct 2016. But while i was entering into the office premises its almost 200 peoples are checked in i was shocked (becuase in ISO 13485 or related medical devices domain there wont be much people) Then i came to the knowledge of all domains like MATLAB, .NET, ASP .NET, including quality etc., all of them had a interview on the same day As i wish only 7 peoples are came for Quality Control, Quality Assurance related to ISO 13485 domain in which some of them doesnt have much knowledge too. so i got selected i think :p After competing F2F interview they gave a Interview Record sheet to fill it up which they gave only to selected peoples and asked me to come for HR round in weekdays within 2 days i got a call from HCL recruitment and asked to upload my paperworks as i did i received a offer letter from HCL
