Capco Business Analyst_Derivatives interview questions

Long convoluted Interview process. The Staffing agency calls up and sets up a F2F interview on a Saturday to Whitefield office. I notified them in advance that I had a personal commitment so will not be able to make it. I was still pestered to take a Skype call. How unprofessional. Then after my return from vacation, I followed up on the interview I got a rude call from the agent but I kept my calm to explain that I was following up. She then rudely suggests if I could take a phone interview that evening itself, I then suggested the next day. The interviewer calls up and asks basic question on my experience without divulging too much into details. On further follow up questions, decides to end the call saying that the next step will be a F2F meetup on Skype. After almost a week I receive a call for Skype meetup. The meetup was setup on 24th Jan - Fri at 7PM with a call letter sent to my inbox. I patiently waited for 30 minutes and send out a note to the Capco Talent Acquisition executive but no response. I am yet to get a response on why the interviewer did not bother to show up or in the best case why was I not notified. Based on this unprofessional experience, I have decided to give it a skip. I would suggest that you stay away.
