I was approached by the company's HR representative and passed a few technical interviews, up until that point all was going well and the company seemed like a potentially good opportunity. At the end of the process, I had a conversation with an HR manager regarding the contract draft, the salary they wrote down was lower than what we initially discussed. When I brought up the salary subject I could feel how the attitude towards me changed and became hostile. I received comments such as: "With your experience, this is what you deserve" and "According to our calculation, you do not deserve more" I tried to filter it and just get to a mutual agreement. The HR manager did agree to meet in the middle and improved the offer by a little bit. Eventually, a contract was sent by email. Although this whole episode raised some red flags, I had just enough time to write a leaving notice and send it to my employer. The next day, during lunch, I received a call from HR stating they decided to void the contract and pull the offer.
