This was a first round interview in London, a very questionable experience but the interview itself was really nice. First, they decided to do this on-site literally a few days before the first lockdown started, it was quite confusing to go to London amidst the pandemic. Second, they literally ghosted me after that, I tried to contact the HR person a few days after the interview, unfortunately, an auto-reply was everything they could provide. Obviously, they didn't contact me later after that. In addition, I haven't got a travel expenses reimbursement as they promised. Unexpectedly, 4 (!) month later I receive an automatic email (that was classed as spam, easy to miss) saying that I didn't pass.
