Indigo interview questions

Got an internal referral and spoke with an engineer on a team I was excited about joining. A recruiter picked up my referral and reached out to me, and we had a good conversation in which she told me she'd reach out to various hiring managers to schedule an initial interview. It took her a month to respond to my two followup emails, and it's now been a week since my response to that email without a reply.

Quick and efficient from start (getting the phone screen from recruiting) to offer. The interview itself was quite lengthy though, including 6-8 individuals including hiring chain and stakeholders. Very conversational about past experiences, hypothetical approach to real business problems.
