WhatsApp Hight Level System Design: Mock Interview experience

not sure how exactly is 80/20 rule applicable here , not making any sense

[@GeekySanjay]

The 80/20 rule, or Pareto principle, can be applied to DAU (Daily Active Users) to explain user behavior. It means that around 80% of the activity on the platform might be driven by just 20% of the users. This helps us identify the most engaged users and focus on features or improvements that cater to them, ensuring that the majority of the value comes from the efforts targeting this highly active user group.

@@GeekySanjay don't think it would be applicable for messaging platforms, it's more suitable for photo sharing or content sharing platforms like RUclips , linkedin , instagram, twitter etc

[@GeekySanjay]

The 80/20 rule can still apply to messaging platforms like WhatsApp. While 20% of users actively send most messages or share content, 80% might only read or respond occasionally. It’s just a different type of 'content' compared to platforms like Instagram or RUclips where we can apply 80/20/1 in social media

@@GeekySanjay respectfully disagree , i still feel whatsapp/ messaging systems are both read and write heavy, anyways it depends on the interviewers.
