Domande di colloquio per Senior Python Developer presso Synchrony

I had three rounds - 1) 1st round was a technical pair programming round where I had to code out the solutions to two problems in python while explaining my approach. 2) This was a HR round with basic discussions about expectations and job locations. 3) Third round was again a technical round where I had to present a topic of my choice. After getting positive feedback on all three rounds,I was ghosted by the incompetent HRs for one week and then upon mailing them back was given the rejected status without any proper reasons.
