I recently interviewed there and they said they're still using Postgres master-slave setup most likely on some cloud provider. Could be catastrophic failure with multiple shards going down at the same time. This might also explain why they mentioned their "backups" not working

I believe they are on AWS, so maybe RDS PostgreSQL. If so they should be getting unlimited support from top tier AWS engineers.

If that is true and they're not on the ball they have another hard deadline fast approaching: https://aws.amazon.com/blogs/database/amazon-rds-customers-u...
(yes: the URI says February 5th whilst the article says March 5th!)

Why would they get unlimited support from "top tier" AWS engineers?
A company like Robinhood doesn't strike me as a strong candidate for contracting AWS Enterprise support. For the price you get almost nothing out of it.
My bet is still on it being a database issue. If they indeed are using AWS RDS, I wouldn’t be surprised if they have half of AWS support engineers working on it. Once again, if I had to bet, I say they rolled their own "half-baked" database solution instead of using a AWS native offering.
