CSE '26 at IIT Bombay. Got into Google after 12 tries. Writing about placements, DSA, and the dumb mistakes I made so you don't have to.
Most DSA tools show you the answer. This one shows you the thinking. Animates state transitions for sliding window, two pointers, monotonic stack, graph traversals and more. You can step through manually and see exactly what is being tracked at each point. Built it for myself. Shared it with my wing. Now 3000 students have used it.
After my 8th rejection I realised I had no idea which companies I had applied to, what stage I was at, or what feedback I had gotten. Built a simple tracker with company stages, interview round notes, and a pattern gap analysis based on which topics I kept failing. Used it through my Google prep.
