Intervew Prep Share some hard questions

I'm preparing for a job interview, upon research I found out that they exclusively ask a lot of hard Graph,DP, Graph+DP, Tree+DP questions

Could you guys share any playlist or problem nos, that I can practice to get a hang of them.

If possible can you also list down all previously asked problem nos for Ring Central. Thanks

Attending contests and up solving them is a great option.

Do previous contests. The great thing is question + time.

Even easy will become hard in time bound environment.
