We were given two written tests - one objective and one subjective each of 1 hour. The objective test went fine and the questions were more or less easy. As for the subjective test, it had two questions - to calculate a rectangle of the largest area of a rectangle formed using all 1s in a matrix with only binary values, to find the largest distance possible between any two nodes in a binary tree. I was unable to solve the first question so I went ahead with the second one. I am sure my approach was correct and I have tried it over and over, it works. After submitting the test, I was told my feedback was poor as the question I did was also incorrect. I told the guy I am sure it was correct but he said the architect checked it (apparently he can never be wrong), so I was asked to leave. I did not argue any further and left. I checked upon my approach with a few friends who cannot find any issue with it either, the only issue is it is not mentioned directly on GeeksForGeek. I expected at least a 5 minute discussion where I could discuss why my solution is correct considering the low number of applicants. I was a bit upset about the elimination first but upon second thought, I would rather not work for a company where people at the architect level are also restricted to solutions mentioned on GeeksForGeeks and cannot think for themselves.
