I completed my MBA in 2010 and lost an interview opportunity due to having less than 60%. I received an offer, but since I wasn't interested in marketing, I didn't accept it. Afterwards, I prepared diligently for a career in 'HR' within the banking sector, but unfortunately, I did not succeed. I've had some interviews for PO positions in banks, but not for 'HR'. Now, I am genuinely anxious about my situation. How can I build my career in the 'HR' field? Is there any chance of starting over, or is my career over?
