Wealth Dynamix Software Developer interview questions

Very positive interview process. Started with a HR screening that led to an interview with a senior developer and product manager, who delved into technical expertise and asked some questions around C# .NET, OOP in general, and SQL. This led to a final interview with the head of development and the head of strategy, where culture fit and competency questions were asked. I received the offer the next day.

Poorly conducted , with decreased sallary offer than initially given. Phone interview followed by onsite testing, technical part and hr consulting. They've called after 3 days to give me offer over the phone, and 2 weeks later to give me salary reduced offer and position for which I haven't been recruited for initially. Cheating company and unprofessional hr.
