Incredibly poor interview process with the hiring manager, had a first stage interview which he said feedback would be given at the end of the week after the interview... I had to wait for over a month just to get a "No" from him, very unimpressed.

Had multiple interviews with London and NY very late in the evening between 8pm and 9.30pm two weeks in a row, as that was the only time they could do. I got to the HR/pre-offer stage and was told afterwards that my questions on hybrid working and offsite visits were not in line with the corporate culture so they rejected me. I had asked lots of standard HR questions but that is all the feedback they would give, which is frankly disgusting after the effort I had put into the process.
