An initial interview, Case study, Take-home challenge and finally a behavioural interview.
My advice with the IC/Craft take-home challenge is to lean a little less on a pragmatic solution and more on a novel/flourishy approach to UI. Canva is a design company first and feedback leaned more on showing something more 'dribbble'-esque. But be prepared to defend any decisions appropriately.
I made it to the final stage and was unsuccessful as I forgot a question, and needed prompting to get back on track. Make sure you jot down notes.
I've rated the interview as difficult based on how unforgiving the final stage interview can be based on my experience.
Note: You may or may not be interviewing with anyone that would be within your own group/domain, attendees are seemingly randomly assigned based on domain. As such, it's not really possible to get a feel of your potential team until after the final round, which was really odd.
Talent team is great at providing feedback between rounds and navigating you through the entire process.
