Please help, I feel lost

Hi, I am currently working at Wipro. I handle the payroll and accounting for few global regions. I have been working at Wipro for the past three years. I am looking for a job change from the past few months because of the slow growth, salary hikes and learning. I have been applying for jobs and I keep getting rejected after submitting my application/ during the interview process or after attending the final round of the interview, one of the few reasons is my notice period at Wipro.

I feel lost and that I haven't accomplished anything in life because of the career track I have been in and the rejections that I am facing. I have completed my BBA and then pursued post graduate diploma in management in distance mode. I also feel guilty that I haven't studied MBA from a B-school in regular mode. I have always been a very studious student and hard working most of my life. And this slow growth is causing me a lot of pain.

I am confused if I haven't been able to crack interviews because of the notice period or because of the type of process I have been in. I have also been thinking on pursuing an MBA. I am 24 now and I don't know which path would be right for me. I don't know what direction to take. Should I put down papers at Wipro and start looking for new jobs or should I go for an MBA? Should I pursue an MBA in a B-school provided that I have completed PGDM? What is the best approach to find/crack a job if this is the best approach?

Please help, any suggestions would be of great help.

Thank you in advance.
