Waste of time. For experienced professionals also initial round is apptitude test. Test paper contains 30 questions. Then candidate will have 3 technical rounds of interview . Questions asked in interview will be easy . After clearing all the rounds they will say you are not selected.

Came for an interview for QA Position. First round- Written Aptitude. I cleared that. Second Round- F2F Technical Round. I cleared that Third round- Again Technical round. Cleared that too. Fourth Round- HR . In this round, they drop a bomb on you that they have a 2 year bond, if not followed then 2lakh fees has to be paid. I wasted an entire day just to know that they have this bond thing. Please mention it earlier so that people won't waste their precious time on you. Don't fool people by telling such important things in the end round of interview process. MENTION IT IN THE JOB AD ITSELF.
