I applied online.

Had a screening call with a recruiter that wasn't very professional.

Had 2 interviews: First one included a technical challenge and the second was a system design interview that I did not pass.

After each interview I had a call from the recruiter providing feedback (that was awesome, way to go Monday).

In a language of your choice, they provide a bunch of classes representing monday.com boards (board, item, field, column) and ask you to print some values. They expect you to do it efficiently even though they do not mention that in the beginning, Then you will have another bit of challenge added and in the end expect to talk about runtime.

System design: Design monday.com automations. That's not a classic system design interview as they provide many components ahead and also say specifically what requirements they want you to fulfill.
