[Design Round] In the second round of interview, I was asked about database (NoSQL/MySQL) since I was from Electronics background(and a fresher) and didn't know much about the same, So I told the interviewer that I don't know much about databases, just the basic INSERT, CREATE, DROP, VIEW queries and what databases are for. He then went on to ask me about OOPs and design some problem like.. multiple stacks in a single array with dynamic sizes and some constraints, after taking some time and explaining this to the interviewer how it would work, I was done with the question.
