    In my entire career as a software engineer, these are the number of times I used: 1. Dynamic Programming : 0 2. Tries: 0 3. Segment Trees : 0 4. Two Pointer Method : 0 5. Tree Traversal : 1 But we prepare for them in every interview. What a waste of engineering talent.

    Have you noticed a small icon on the right of LinkedIn profiles? It tells you how closely you are related to a user (1st, 2nd or 3rd-degree connection). How does LinkedIn do this?

    Every business is a for profit entity. Jobs exist because the business turns a profit. Unless you work for a loss making PE/VC funded startup. Very important to justify the value you bring to the company when asking for a big hike.

    Your six months of interview preparation means nothing to them. Coding a hard problem in 45 minutes means nothing to them. Your sense of injustice now, also means nothing to them. --- STOP wasting your time with irrelevant DSA problems. Learn real-world engineering instead.

    Indian tech influencers are reacting to DeepSeek in hilarious ways. "Why can't we build our own LLM? What's stopping us?" Nothing. "Shouldn't India have its own LLM?" If there is a clear need, then yes. If it's for fixing your hurt national pride (China did it, so can we!),

    Why are we lagging behind so much in AI? Founders are not starting up in DeepTech? Investors are not being Bold? Lack of Talent? Lack of solid Research Labs in Universities? What am I missing?
