I have started preparing for interview from last 20 days. I am solving problem in leet code, reading some interview preparation books and subscribed to object & system designing courses. And I am almost good in behavioural round. And I am expecting my interview around next week.
So can any one help me proritize the topics which I mentioned above.
**1. problem solving

2. object oriented design
3. system design
4. behavioural skills**
   **With limited time which topic I should cover first ? Please give a direction for me.
