The process should have been very straightforward HR, then team lead and panel conversation. Where they messed up in my case is that the HR person that set up the call did not show up to the meeting, to then find out, only upon me enquiring that they left the business. Then had a conversation with another HR person, who was quite nice, but then took over 2 weeks to get back to me and only after chasing. Overall pretty bad process from these guys.
