5G Wireless Communications interview questions

The company seemed very reputable and I liked the idea of the high OTE of £70 000. I was expecting a very professional interview. The problem was after all my preparations and effort to get to this interview I was not treated in a professional manner but asked at one stag to quack like a duck? I went along with the idea and was selected to go through to the next round which was a face to face interview. After selling myself and giving a great set of achievements and skills the interviewer said you can have the job. Sadly when I asked about the base salary he said it was £17 000 for the field sales role and £13 000 for the telesales role. I had never been so angry in my entire life at an interview. As this phony company (Excuse the pun) was a waste of time Stay away unless you enjoy being paid minimum wage Regards
