First Round. 1. 2 code snippet given to tell their outputs 2. 1 nested 2d array of object problem was given, the output provided was itself, therefore took sometime to solve the question, also shown the interviewer that the output they gave is wrong, then he agreed on the same, also generally interviewer avoids usage of built in functions, but may be they were expected to use them , i coded raw. It was a recorded session. After answering all these questions correctly, first got response next day, that feedback is positive but didn't get any official confirmation and at evening same day, got negative feedback, that they were expecting to resolve in less time as per your experience. My first question is why the hell you are giving the incorrect output itself first for the problem, it will take some time only then right, but still resolve and gave the correct output within the interview time. It seems wastage of 1 hour for me as the interviewer itself wasn't seems capable enough to clarify and give the correct result itself he want.
