yeah, that's what i've had to do. really wish they didnt require ip during interview or whatever. would be happy creating a protonmail account so they could verify im not spam but my ip is a no-go.
out of curiosity, do they ever use that ip again after the interview for tracking or account recovery or soemthing? like if i signed up from a coffee shop or bar or something while travelling, would it ever be required again to where i might be fucked if i needed same ip?
