Jane Street Desktop Support Engineer interview questions

Probably the worst interview experience I had. Interviewer just went into asking technical questions, some of them being rote memorization questions, like "What does BIOS stand for?". Launched straight into technical questions with no background on the company or role. No feedback given at all after responses. Sounded completely disinterested, like the interviewer was just reading questions from a document. Probably a red flag when the second question they ask is "How would you deal with a user who got angry with you?".
