I passed the practical interview (first visit) and verbal interviews too (second visit) and was even called and told that I had been selected and even given a job offer (verbally). The HR invited me to sign a contract the next day (third visit), but he kept me waiting at the reception for more than two hours and finally told me to go and that he would contact me, which he did (multiple times). He kept adjusting and readjusting the proposed salary in the calls, making me suspicious, and I declined the job offer.
