Courses like one offered by InterviewBit provides a lot of candidates with a clear curriculum to getting a job at a mega-corp like Google, Amazon, LinkedIn, Microsoft, or Facebook. Think of it as a highly specialized course in Interviewing. Of course, the right approach would be to what Recurse Center and the Insights Foundation are doing... focusing on the means (gaining expertise), rather the end itself (getting a job, making an earning); but that's not a priority in a country like India where STEM graduates by the millions graduate every year and only a smaller percentage of them land jobs at a "dream company" as it were.
I personally think InterviewBit is an excellent product/market fit for a country like India. They're also good acquisition targets for companies like HackerRank, and LinkedIn.
