Capital One Senoir Software Engineer interview questions

Phone screen, then on-site. 2 behavior, 2 technical. I like the fact that the company puts emphasis on technology. I like the people I met. However, the senior software engineer who interviewed me asked me some ridiculous questions such as "what is servlet concurrency model", "what is jersey concurrency model". I was completely confused. I've never heard of such questions before. He asked me to write a program in go, one sends message, one receives message. I was also confused. I asked him whether he wanted me to write one program or two programs and then he said write in event model. I completely got lost. Does he really understand how channel works in Go? He then asked me about RabbitMQ, He asked me how do you handle transaction in rabbitMQ, I said there's no transaction in rabbitMQ, then he said how do you use JMS with RabbitMQ. I was confused. It's like he really wanted me to use JMS with RabbitMQ. It's obvious he's never used RabbitMQ before. Why would I want to use JMS if I pick RabbitMQ? I was rejected because he gave negative feedback. Some careless people could ruin your chance!
