Coviam Software QA Engineer interview questions

Interview was good and interviewers too. 1st round was Aptitude which was not hard and not so easy also. Do practice before going. 2nd round was technical, where they asked self introduction, to write bugs on BMTC application and asked few of the software Testing related questions followed by some Puzzles. 3rd round was also technical and there were some software testing related questions and full of puzzle questions. Got rejected after 3rd round and all credit goes to Puzzle questions. Don’t know why so many puzzle questions though it was a QA Manual Testing engineer profile.
