For Ffs , why don’t I get to see questions like: a) How did you learn execution in the Product management during the initial years? b) What is the basic difference between Webhook and polling? c) Why and when should one use JWT? d) what are some of the problems that are unsolved and can be unriddled using Generative AI? e) Criticize moron founders who are still copying apps in 2024 like literally stealing UI ( Check the Sasta Duolingo from Gaurav Munjal, bhai Matlab bas colour change kar diya and copied Duo lingo ka interface) f) Why checkout finance is shit product and destined to fail? g) What exactly happened with Slice? h) What do we use Kafka for?
