I applied online. The process took 4 weeks. I interviewed at Graphcore
Interview
It was a timed 2h take home quiz on coding. The interview feedback was that my experience in some particular area was lacking gaps, even though this was not part of any assessment that was done after the CV review.
Interview questions [1]
Question 1
They asked me to go through my responses to the coding challenge (which was a timed exercise and I no longer had access to the questions, nor did they, seemingly).
