On November 20th, the "69-year-old" programmer agency recruited Ping An Technology, and the interviewer asked me to "do it for myself".

Just now there was a young man on the phone, weighing more than ninety kilograms. The young man slapped it. Soon, one high concurrency and one distributed. I care about it. I didn’t answer it. The traditional interview point is over. I said you guys don’t talk. Wu De, he said he asked, he didn't ask, he came prepared. I advise young people and rats to feed juice. The problem of social recruitment is still the problem of school recruitment. Social recruitment should emphasize harmony. Thank you friends.

Teacher Ma has been very popular recently, and I have been playing around. Of course, the interview experience I want to see today is definitely not 69 years old, so don't talk nonsense and look at the question.
