HELP !!!

I was in manual testing for 2 years. Left my job. Joined scaler. Cleared some mock interviews (except DSA). I am in desperate need of a job in developer role(full or backend). I need to clear DSA and ReactJS mock interview in order to be eligible for placements at scaler. I don’t see any other option now. And talking about DSA I don’t feel confident enough. Sometimes I go blank when there is a question. I don’t know to prepare DSA smartly and fast. Kindly suggest what should I do. (I’m not that bad at DSA. It’s just I’m not confident enough). So.. I’m open to all kind of possibilities and suggestions.

How to get better at DSA?

I am a backend engineer with a 9 year exp. In my fourth company now. Started with 5 lpa, now at 31 Lpa. Mostly have worked in normal companies only. I am from one of the NITs. I am not good at DSA. Everytime I have to switch a job, my resume gets shortlisted and I get call via naukri. The things is in these last 4 job searches I have been rejected 100 times. I have been rejected by almost all the companies, Service now 5-6 times, oracle 5-6 times, Walmart 2 times, goldman 3 times, jpmorgan 2 times, Amazon 4-5 times, arcesium 3-4 times, msft 2 times. Apart from these, I have been rejected by adp, celigo, phenom, barclays, flipkart etc. Every time, I want to change a job, I'll get rejected by all the big companies and then will get selected at some normal company with a hike and will join them. I am at my fourth company now, and again I am searching for a job. Have already been rejected by GS, service now, phenom, epam, ice, demandbase in last 2 months. Every time it is the same DSA. I try studying, will do decent amount of leetcode prior to interviews. Last two months I am doing leetcode from strivers sheet. But same question I'll do here, and in interview will fail. Example I have done sorted array rotation, shares sell and buy, rain water trapping, and was asked the same question in interview and couldn't solve. I also want to earn more and get into some big company and stay there for some times, what shall I do? My concerns are, I am getting lesser calls this time compared to the last few years, I can't be switching job every two years. Want to join a big company and earn more.
