UpStream Global Services interview questions

I had 4 rounds of interview, in the third round the global sales head told me to get a PPT ready on Sales plan on their Product & services, asked me to get in touch with the HR, I called HR Jisha who told me the HR director will give me the information, then she calls and says its in the email which has the JD. I spend 3 days to get the PPT of sales plan ready and submit, the Global sales head calls me and tells me he didn't want me to create a sales plan on Imagility, the weblink of which was shared by the Jisha the HR. Then asks me to redo the Ppt in 90 mins, I prepare the new ppt and share it, I have a an interview with their CEO, who wants me to know their already best selling services by looking at their website and he expects me to sell a ticket size of 500K USD without even knowing their services, I thought the interview was only to understand the strategy of selling. And after the interview nor the HR or HR Director calls me to tell me they have rejected my profile, I have to call the HR two days after to find out they have rejected my profile. Unprofessionalism at its heights.
