the first round of online interviews - recorded online in real-time, timed answers, felt a bit mechanical because of that, but I realise that it is a necessary first stage with the amount of interest the company receives.

The questions themselves were very standard, but what threw me slightly was being asked to choose a painting from a selection on the table and talk about it, without knowing anything about it prior. I appreciate that they give feedback over the phone after interviews, though -- it makes the process less opaque.
