I submitted my resume via LinkedIn and was contacted by a recruiter 2 days later. Had one phone then onsite interview.
Phone Interview:
A little about Meraki and my background. One bit manipulation question followed by a graph search problem. Average difficulty.
Onsite Interview.
More about Meraki and more about my background/projects. Questions were fair! Bit manipulation, graph search, linked list, arrays, stacks, queues, maps, algos., etc... Hard interview because of so many (7 interviews total). Otherwise question difficulty - average/hard. Make sure you can code on a whiteboard.
Overall, my recruiter and interviewers were awesome. After this process and a tour of the campus, I know I would be working with smart people in a still startup like culture.
