Ciptex interview questions

I went through three stages of a four-stage interview with this company a couple of years ago and decided to withdraw before the final round. From the very first stage, I had a negative impression. One representative, Thomas, made undermining remarks about me being from Poland (e.g. suggesting I should be paid in PLN). The company also insisted on knowing my salary and falsely claimed it was required by British law. The overall experience felt unprofessional and broke my trust. I chose not to continue, even though I had passed all earlier stages.
