In a week or so I'm going to have a online coding exercise for about 2-3 hours with Goldman sachs. I have no idea as to what they might ask as they said they'll share the problem statement on teh day of event.

Background:
I have gone through 6 rounds as of now.

1. HackerRank
2. Coderpad+telephone
3. 4, 5, 6 Fae 2 Face (coding + team intro + projects all were covered in these rounds)

Now I have been invited for this Exercise, Anyone have any Idea what that can be? or if anyone has gone through the same?

Please share your experiance or suggestion for what to expect, will highly appriciate it.
TIA
