Phone call with recruiter.

Online technical screen - timed for an hour.

Onsite with O365 team (4 simple questions).

Could not gauge their feedback to be accurate, but that may be because I didn't get it.

They seemed like a mass hire team, so make sure you understand the job requirements and how you fit in.

Overall, nice people, but very hard to read.

Feedback while doing the questions was pretty minimal. Their involvement seemed like they wanted the correct solution that they knew of and end it there, or you're done but I'll still give you a thumbs up approach.

NDA - but read up on basic questions regarding string manipulations, trees, and novel data structures that allow for space optimization and relatively faster lookups for similar values. ;)
