Interview
I am from ECE(Electronics and Communication Engineering) background. There are 2 rounds of technical interview and both of them are one on one interviews. For me first round was a bit easy one and I felt some what tough in the second round. Both the interviews started with "Tell me about yourself??" and then they started testing my technical and coding skills. They asked about OOPS, cloud computing and finally asked about the projects that I mentioned in my resume.
