Meraki Senior Software Engineer interview questions

I spoke with a recruiter first. Then another recruiter. Then one more recruiter, who finally (a week later) asked me for availability next week for technical interview, which I did, and she disappeared for two weeks, and then asked me to provide availability again. Finally, there was a technical interview, during which I was asked to optimize an algorithm for not keeping a 7 byte string in memory (I kid you not, 7 bytes). She had her solution in mind and would not stop talking about it, so I didn't have any time to think about my own. Finally, we just ran out of time.

Applied thru linkedin. Got an email from HR and setup a time to talk with recruiter. Recruiter discussed past experience and skill set. Got an email from HR to setup a tech screen phone interview for an hour. Got a call from a senior architect and discussed technology and was asked 'how would you go about' scenario questions with technology/logic solutions. HR coordinated for a in-person interview @ HQ for 1/2 day. Met with Recruiter, Manager, CTO, Architect, Senior Developer and Oprations-in-charge. 2 of those were technical and the rest were behavior/personality type of questions. HR gave a tour of office and explained about the company. All the interviews went really well (or so it seemed to me). HR informed about getting back in a couple of weeks after they complete interviewing everyone they were considering for the position. No correspondence since. Everyone was very courteous and professional during the whole process.
