This happened 2 years back. I initially applied for another role but the timelines didn't match. I reconnected with HR 1-2 more times in the next 3 months, then she remembered and reached out to me 2 months later with another opportunity. The entire process was conducted online, maybe because it was fresh out of the pandemic: (1) First round chat with the manager went well. I was informed that I would have 4-5 days to submit a case study and present it in the next meeting. (2) In the second round, the manager was walking from place to place on the call as I presented. I thought it was slightly unprofessional but shrugged it off as he had apologised at the start. He gave his feedback and told me to amend and submit my 'optimised' slides in 2 days. If the revised version is satisfactory, then I would have a third round to present it to management. By then, I had spent a lot of time on the case study and preparing for each round. I was turned off by the process but thankfully, this let me see the red flags...
