TrustYou interview questions

I had a bad interview experience. I started the interview round with one vacancy and at the same time during the recruitment call I was offered to also apply also for a second vacancy. After going through the series of the interviews namely Recruitment, Technical and Team Fit I got the email saying that they filled in the vacancy and no feedback to my interview. When I asked about the second vacancy I was told that they will be in touch and never contacted me, however after a few days I saw that they published the vacancy on Linkedin.
