Included Health Software Engineer(Multiple) interview questions

The interviewer was good. He asked me several questions about the challenges I have faced in the past in my interviews. He used to cut me alot in between without allowing me to proceed. May be he was trying to see something interesting in my experience or totally ignoring to what I was saying. Later after 20 minutes , he jumped to the hackerrank and posted a question. I was not sure of boggle game but I knew that this problem was similar to the word search from the grid. It took me a bit longer to think about the solution. But this was definitely the hard problem to resolve in 45-50 mins. Later the interviewer asked me if we can do this in any data structures, I thought of Trie but since I am not much aware of trie Data Structure, so I did not proceed with the solution. He asked me about the time complexity, answered him.
