To all sql guys,
I have just started my pl/sql interview preparation. The medium level questions are taking more time to resolve. I try different methods I know for an hour and give it up. I then jump into the solutions and understand how that's written. I am not sure if this approach is correct. How are you guys preparing for a database interview. WHat is your recommendation?
Some questions I have are

1. How much time should I allocate for a query before moving to another query.
2. What should my strategy be if I am unable to solve the medium level questions?
3. How may hours do you allocate for LC sql queries every day?

Appreciate your response
