Interviewed for them this year.

Got into a heated argument where the interviewer insisted it was perfectly acceptable to store money as a mutable row in a database.

I pushed back with the standard "You append transactions (including corrections) to a ledger" but he wasn't convinced.

I whipped out the standard two-ATMs -separated-by-a-distance overdraft example, and how you can create or destroy money that way.

He said it made no sense as an example because it was buggy and you would never release buggy code.

I asked if he'd done bug fixes before (yes) but obviously he was going to keep digging in further.

The irony of it was that he was part of the blockchain team.
