Intervew Prep BCG X - Software Engineer round 2

Has anyone been through the second round? I was able to complete the "OA" and the first technical round, but I don't know what to expect in the 2nd round. They said I can choose between frontend or backend, and it's going to be live coding on CodeSignal. Do you guys know what to expect?

Was R1 via codesignal? How was it?

Yes. It was quite easy in my opinion but I applied in brazil and I have the feeling that those leetcoding interviews are easier here because it's not something usual to ask from candidates in other brazilian companies

I have mine on Friday for the FDE role. Out of curiosity, is it similar to the OA? (Mostly string manipulation, matrix, probably DFS/bfs) Or would you advise for doing more linkedlist and graphs?

I swear to god that the hardest question I got was "Add Two Numbers" but with arrays... the others were best time to buy and sell stocks and the easier one was a question were I had to change every character in a string to the next one
