Telephonic: 1. Java Question 2. Selenium question I can clearly see the interviewer is copying the questions from some websites/files & pasting it to Collabedit.. When I solved the problem the interviewer himself trying to understand the flow.. He was not well prepared. F2F: Asked 1 java question & I have solved it two ways.. When he changed the logic he himself given me a wrong solution for that declining my correct one.. He was even asking me GIT commands which which is not even required in daily work.
