Are you hitting my spam filter or something? We have a group of 4 people that work together to handle the mail we get at careers@. If you send something and get no response, you can escalate, like you're doing here.
(I can't answer the question I just asked myself, because I have no idea who you are. Sorry!)
I don't know what else to tell you. We don't ignore mail to careers@. For instance: the H1B cap is now closed for the year, but we're still replying to people who would need a visa to work in the US.
It occurred to me a minute ago to tell someone else to mail me at my personal address; you can do that too if you like. I'm thomas at sockpuppet.org. Pretty sure that won't get spam filtered.
I'm curious as to whether you have some further complication than spam filters here. I got as far in your pipeline as answering one email about what location I'm interested in, and then heard nothing more. This might not be news, but if you're having trouble getting other messages it also might be worth knowing.
