Why CS Careers before 25? Velez Real Talk on Opportunities in India.
Suppose you do this at 22 years, you can code AI models at startups or projects in ISRO earning 8-15 LPA. There is an increase of 20 per cent annually in the fields in CS in India and the overall number of jobs will be 2 million by 2026. The careers of data scientist or an ML engineer do not involve any decades of experience but intelligent entry points in UG programs or combined classes.
But how? Post-Class 12 crack permits, follow a major of their choice, secure internships, create GitHub profiles, and become a specialist prematurely. Quite a good number of IITs or GCSET colleges are hired to the junior scientist post by 22-23 years. No delays acceptable: Aim at 4 year B.Tech, not interminable pre-training.
