A simple interview with the senior researchers, which mainly focused on understanding of system knowledge and past, will surely play a pivotal role, and also, some recommendation letters are recommended for this institution

I applied it through email and arranged for the interview after few days.The interview was by phone and they basically just want me to talk about myself. After that, I asked some questions about the company and the projects. I sent a thank you letter after few days, and they told me they found someone else.
