I asked for a specific salary in my first discussion with the HR and they agreed. After four interviews and solving a business case they told me I got the job but their offer was much lower than what we initially discussed. Of course, I declined the offer. It was a complete waste of time and one of the most unprofessional experiences I have ever been through. I strongly recommend you to avoid this company. If you want to be paid below the market level for doing a complex job apply to their positions.
