Bühler Group Process Engineer interview questions

The interview went well, the manager taking the interview liked me and I got to know from the consulting company that they will hire me. We signed a contract with the consultancy company. I got a call the next day from the consulting company, that the HR in Bühler decided to cancel the contract. The reason was, I think, that my husband was working in a company, that they might have had some competition issues with. So I went through a big shock and we relocated to another country after this case.
