Qwinix Technologies Sr. Python Developer/Software Engineer interview questions

Don't waste your time attending the interview with Qwinix/Cloudbakers. I have given 5 rounds including the HR(Salary discussion) round. The last round was taken by the Senior Consultant-HR and agreed to generate the joining letter the next day but when I called them after a few days they said that the opening is on hold. They could also call me back and inform me of the situation but they didn't. Seriously!! Is this professionalism? I don't know how they became a Google Cloud partner. They are also spoiling the name of Google.
