Round: Technical Interview
Experience: It was 1-to-1 interview where I was asked about the previous projects first. They have asked everything about the project, from why we chose the technology we chose and how we implemented it.
Tips: Can't give much tips as I have not faced many interviews myself, but as far as internship interviews go, they require candidates who are willing to learn. You don't need to convince them that you know everything, as the basic understanding of the subject and willingness to learn will do just fine.
