Revolut Senior Software Engineer (DevEx) interview questions

Recuitrer reached out to me over linkedIn, First call was with HR which was pleasant, we both discuss about the role and other details related to that . 2nd interview was the live coding session which was with the one of the member of DevOps , Recruiter already mentioned that test will be related to the 2D array transformation for which i prepared myself very well , Task: Create a function or class to print a matrix of size x * x. Fill it with y mines. Mark mines as 'x' and mark empty cells as '0'.Mines should be randomly distributed The one who took the interview was very friendly . Unfortunately couldnt make it due to some silly mistakes.But i might help someone to prepare for the interview.
