Preguntas de entrevista para Bitrez

I have been contacted by a recruitment agency working for Bitrez via email. The job title matched my experience and the salary range listed was 28000-35000 which got my attention. I followed up with a phone call the next morning and I was told that they pay 12.6 GBP/hour so the salary would come to "just under 28000 but there is possibility of overtime". I ended the interview there because to ask for an experienced scientist when all you are willing to pay is pennies above the minimum wage and to not even have the decency to be transparent about is an absolute disgrace
