Interview Preparation Tips
Next round was taken by Senior Team Lead. It seemed as if did not even care about the interview. Gave me the question and did not even bother to check the solution. While I was discussing design for url shortner, he did not utter a word during the whole discussion.
I felt positive as he did not counter question my solution but HR said I was rejected.
