I only was able to the first round and it was moderately difficult. It was codesignal industry coding assignment. You’ll be given a progressively harder question across four levels and your task is to write maintainable code that solves as much as you can. Take the practice test to get familiar with the timing and format.

Great experience all-around. They give you very clear information ahead of each interview round on what to expect. Everyone was friendly. Standard interviews for a researcher position (coding, ML background, research talk, culture)
