I have friends outside of Citi who are highly technical. They are already currently employed at fortune 100 companies and aren’t on any layoff list, even so, they keep their options open. I have submitted them for various positions at Citi over the years. Upon this past submission I was informed that they decided to put any Citi employment seeking to the side. This being as they’ve either submitted and heard nothing or interviewed and heard nothing. No “we don’t want you”, just nothing.
So they decided to blacklist Citi altogether but it goes beyond that. There are networking forums, group WhatsApp chats and such, those beyond LinkedIn, that tech people get together and discuss which companies to forget about for various reasons such as rescinded offers, cancelled interviews, etc… Well it seems that Citi has made the list, not that they really care of course.
