Round 1: screening - online hackerrank test (2 questions) - > They were easy level problems, I was able to solve both. Round 2: Tech discussion with Interviewer -> some python questions - > Find the co-occurrence of words in a line, we have to write two methods (push and check) It was an easy probleml, I came up with an optimal solution for check - O(n)T and push O(1)T. The interviewer wanted the other way, I did that too with the help of the collection class. He was not happy with the fact that I'm not aware of the syntax of the particular collection (I offered to write my own helper method though) I did not get to progress to the next round. Not sure what went wrong.
