Worthix Machine Learning Engineer interview questions

The interview consist 4 rounds. Mostly about NLP cases and one coding case. They told me before the final round that there was another candidate they are considering, and after the final round, they cut me off without saying anything. I tried to follow up with them but was completely ghosted. I spent 4 hours of time just to talk to them, and at least another 10 hours to prepare. Their choice of ghosting me was very disrespectful and I am sure I won't be the only person to receive such treatment. Avoid this company if possible.
