I could do only one operation which is turn on and off the bulb and for every bulb on which I applied this operation the state of all bulbs to its right will be flipped. I had to tell the minimum no of operations needed to switch on all the bulbs. " Round 2: Given an array of strings I had to group all the anagrams together efficiently. A system based kind of question to design a twitter like application .( The interviewer told me to express my ideas without being afraid.)

What should be the preparation strategy for an aspiring candidate?

Standard Data Structures concepts and DSA questions are a must. I would recommend doing either leetcode or interviewbit completely. Apart from this competitive programming also helps a lot and a couple of decent projects before the intern season begins.
