The interviewer was very polite, he firstly asked me to introduce myself, then he went through my resume and asked me whether i have any technical skills or not. I said "Yes Sir" and I told him about my skills and projects. He asked me to write the code of merge sort, then he gave me an array and asked me to dry run using this array. I did that. He then asked me a question to reverse words in a string, eg: I/P: how are you O/P: you are how I did this using stack. Then he asked me a string based question. I/P: AppLe O/P: aPPlE Firstly i used in-built function to solve this but then he asked me for another approach, then i solved it using ASCII values. After this he gave me two puzzle, I solved only one of it. Then he asked me some basic SQL query and Operating system questions, I answered that. Then he asked me if I have any question, I asked him about the tech stack on which company is working. He answered that.
