My GF has two nibbles on her resume, and both want her to communicate through either Signal or Telegram.
Edit: they requested banking info right off the bat. Said they use it to “confirm you have a checking account” to verify eligibility. Blocked them on Signal, reported to Indeed, for whatever that’s worth.
Unless it’s for a position where that’s the standard, e.g. certain investigative journalism roles, I’d call it a red flag and have the scam sirens blaring. Although as a cybersec professional I’d be VERY curious to see where it goes and what their deal is. I’d MAYBE expect some security roles to request E2E encrypted email comms at a certain point in the hiring process depending on the project, there shouldn’t be anything discussed pre-onboarding that necessitates using Signal.
