Interview in 2020 for London, I had one phone call interview that was competency based, then followed by an online coding interview and finally a final round consisting of 5 interviews. One of which asked logic questions and riddles, the others a mixture of design and coding.
The interaction wasn't great with one of the coding interviewers who put me on edge who keep criticising the approach. He also had a shadower who wasn't clear in explaining the second problem.
The riddle questions were interesting but frustrating and as I thought these questions were no longer industry standard. I believe there was some miscommunucation with the interviewer as I verified my answer on google afterwards (perhaps he thought I was talking in riddles).
One coding interviewer was excellent, well articulated the question, the interaction was good.
Despite the time and effort to prepare, I had to chase a few times to get the verdict and there was no feedback at the end.
