Now that you have your Commercial Pilot License, you need experience in terms of flight hours.  But landing with a job into a big airlines is quite difficult as a fresher, since all the big companies ask for experienced pilots. Now what you can do is you can apply to small and medium sized companies and work for them and gain some experience. Targeting small and medium sized companies do hire freshers and can help you land a job there. After around 250 flight hours, you can apply to well renowned big companies and get selected as well.

After selection to any of the companies, first you need to work as a Co-Pilot or FO and then you will be promoted after more experience.

I wish you all the best for your future endeavours.
