I don't generally comment on my employer, and I especially don't post about their internal policies. But I think it's reasonable to post this much, insofar as it's also a question I'd also answer for anyone thinking of interviewing: no, there's no MITM proxy. (There is a proxy; it does not MITM.)

1) You can't downvote people who reply to you. 2) Discussions about downvotes are off-topic. 3) Downvoting to express disagreement is explicitly allowed.
