Is there any opportunity for a fresher who is pursuing a data analyst course from Coding Ninjas, with a 4 yr gap?

Start with cold-applying to all and any startups you come across. First few years will be hard and you will think you are being paid way less than your peers but keep learning and building a good profile. Fir tumhara time ayega. There's seemingly no other way to navigate the current market scenario. I wish you luck for your job search!
