I designed and built one of the first graph databases. A graph database was at the core of Plantir's software. I also had high level, difficult to obtain security clearances.

I had a phone interview with Plantir. The told me that the next step would be a software test and whiteboard software interviews. No questions about what I had built (which was unclassified- only the applications were classified).

I didn’t want to go through this process which would have been more appropriate for a newly graduated software engineer, so I declined to go more interviews.
