QuantumBlack - Data Engineering - First Round Technical Interview

Hello everyone, I have a first-round technical interview coming up. Have been told there will a 15-minute session on technical questions and then a 20-minute coding exercise on codepair. What kind of questions should I be expecting? Should I revise DP, search algorithms, trees and graphs or should I focus more or almost exclusively on SQL?

Please someone help me. I am stressing a lot and am unable to come up with a plan to study. Please if someone knows how to go about help me. I shall be forever grateful.

PS: I realize this a finance forum. I am posting here because it is a very well-known forum and I may be able to receive some guidance.
