F2F interview about team management and product specific technical knowledge. Even after correctly answering 99% of the questions - feedback from HR received was negative as received from interview panel. Totally biased for regionality. They just want people from a particular region and no value for knowledge or skills sets. Might be just worthless to attend interviews if you do not belong to place from where your interview panel comes from. Your knowledge and skills are irrelevant. Seems they might take you even if you know nothing but just belong to a particular region.
