Kern (Switzerland) interview questions

Good interviews with local management team, assistant GM, GM and Swiss owner over several dates. A job offer was made. Contract & acceptance letter signed and returned with a start date of 26th March 18. Further written communications asking me to cease my current contract as a self-employed consultant to a Turkish company. I duly complied with the request, having already accepted the Kern job offer. Further communications re company car and accommodation during the first week of the new job. CRISIS - Kern call 16 days later to retract the job offer!!!! What sort of morals and leadership is a play here??? Having conducted interviews over a month and made me an offer they stoop this low. At this point, it is impossible to reinstate my client contract. Disaster!!!!

Informal, pleasant, straight forward. Promise of learning environment and career growth. The interviewer and HR manager inquired of my imput concerning continued education and growth in this field and if I considered it important? Asked how long I had been in this field? They also wanted to know if I had any IT certifications?
