Switching to Indian startups job

I am working remotely at a SaaS company for 4+ years now. I started working since my final year of engineering. I joined here as a software engineering intern when the product was really new and booming. I have gotten bored of my work now, especially since I have been working from home all the time. I have very little social life. And I am getting fixed salary of about $1400 each month. I am thinking of switching to any Indian startup because I am not happy with my job being so monotonous and less pay at this level of experience. What should be the approach to crack the interviews? I have done DSA practice during my college days, but didn't crack any interviews with it. I am a full stack web developer but it doesn't excite me anymore and I want to stick to backend roles. And is it possible to crack an interview with for 30-40 LPA at this stage? Or do I have to climb up a salary ladder for a couple of years?
