Online coding test, followed by face-to-face on call interview, followed by data task (on their own data), then a on-cam coding interview in which I got rejected. I felt like they made me work for free on their own company data and were difficult when I asked for feedback on the rejection. I had done well through the rounds and was confused about the reject. At first there was no response but when I strongly insisted, they were sarcastic and lied to me saying that they were too ill to respond to my feedback requests. So, they were not ill when sending the rejection but became ill within minutes as I asked for a feedback?! This was the lead of operations there. If they can resort to sarcasm and lies for a helpless candidate, I wonder how they deal with their clients. I now feel lucky I did not make it, or I would be working with horrible people and never know it!
