Graphcore Research Scientist interview questions

I received an email about a month ago with a link to an online test. Please attempt it after practicing MCQs or revising linear algebra, data structures, and algorithms, as the test is quite difficult. After that, I had an initial call with the lead, who explained the interview process. He mentioned that there would be four to five rounds in total. The first stage was the live coding exam, which lasted an hour. The next stage would have been a paper discussion, involving reviewing and discussing a research topic. Unfortunately, I was only able to progress up to the coding exam, after which I was rejected.

Initial online test (~20min): - fairly basic, but fast - some ML and maths/stats knowledge Online interview: - some discussion around the role - primarily live coding problem In-person set of interviews: - discussion of ML paper - technical deep dive - ML breadth *Plenty* of time was left for me to ask questions about the role: from how the team works to the minutiae of role. The team were very welcoming, and gave a lot of their time. All the interviews were done very well. The interviewers asked probing and suitable questions, enabling me to demonstrate my skills. It was the best interview process I went through.
