Ericsson Performance Test Lead interview questions

I was contacted by email two weeks after submitting my CV to arrange an interview for the following week. From application to interview = one month. I was interviewed by two of the Spanish team as they worked down a basic tick list of questions. Some very basic jMeter questions that should have been aimed at a more junior applicant and one interviewer got upset that I asked for more difficult questions. I ended the interview early as something was definitely wrong here
