First, They took the telephonic interview and called for the f2f interview. I reached @ 11:30 AM as per scheduled time and got the form to fill, that I submitted after 15 mins. after waiting for an hour Junior resource came and took the interview and said Senior Manager who was supposed to take is busy and wait for some time. I waited 2 hours and there is no information even lunch time came up and still no information. then I called to the lady who took my interview and she replied that will give me a callback. Again I waited for one more hour then another interview took my interview but not the manager who was supposed to take and informed me that you have to wait for 2-3 hours more, Manager is busy and asked for skype or hangouts. I sent an email with details, no reply yet. Overall very unprofessional.
