Stryker Service Centre Engineer interview questions

After sending my CV the next day they sent me a reply that my CV was selected and that they would like a telephone interview. I chose the timetable according to my work possibilities at my lunch break. They called 10 minutes after the agreed time, the recruiter Candidate Care Specialist, she spoke to me on a very poor quality speakerphone where I could hear very badly, I had to ask her several times to repeat the questions, then I could hear noises in the background, like knocks as if she was doing other tasks. Sincerely it seemed that he disliked his job, one of the worst telephone interviews I have ever had.
