Directly contacted by HR through online profile. Phone call from HR for setting up the L1 interview followed by a Skype interview. Conducted for almost an hour and was told Mastercard would reciprocate within a week and if not, could directly contact HR and find out the status for L2 round. Sent two emails to the same HR two weeks in a row and no answer till date. Extremely unprofessional for avoiding a simple rejection response.
