FastInfo interview questions

I had a worse experience interviewing with them. Over call I told them clearly that I work as a content Strategist and not associated with core technical aspects like SEO audit. Yet they called me for the interview and made me write around 2000-2500 words. After that they made me wait for 2 hours and let me go without any further clear communication. I found their attitude and hiring process very unprofessional where their only focus is to hire the candidate who asks for minimum salary. If you do not have budget why waste candidate's time like this and then completely ghost them? My advice would be clarify everything from beforehand before attending interview with them.
