How can I get a job in Airline from the CONVENTIONAL way?

I know it's practically impossible to get the job immediately. According to my research, if I take some job as a flight instructor, I can rack up flying experience and get hired into an airline. What other jobs are there similar to these which I can use to rack up experience in india immediately after CPL? How much experience would I need to actually have a chance at being hired into an airline? And how long would it take approximately.
