Upcoming Goldman Sachs Interview (round 2)

The first round was a coding round on coderpad where I was asked 2 questions - 1 LC hard, 1 LC medium When the 2nd round got scheduled, the HR told it's a coding + technical discussion and competency mentioned in the interview invite is Data Structures.

Since I've only 4-5 days, what should I focus on in regards to my preparation given I'm a working professional? Any tips and suggestions are welcome. Thanks in advance!
