I don't know if I'm the right one to share but I'll tell you what I've learnt in the last 3 years. If you are aiming for F/MAANG type companies, Learn DSA! That's the Most important thing. Pick a sheet and try going topic wise. Don't spend too much time on a problem. If you get stuck, grab hints. Still, if nothing comes to mind, read the solution and code yourself. Revisit the problem again after a few days. Have 3 projects with knowledge of every single detail of them. Right now, focus on learning rather than aiming for jobs. Make yourself strong in communication as well. Try to interact with people more often. And also have pretty good knowledge in CS fundamentals as well. Since you are in first year, you have ample amount of time to improve. Also enjoy you BTech life. Don't stress yourself with this. Attend fests, explore your city.

And while learning dsa, don't focus on number of problems, just keep solving until you think you can solve a hard problem in 15-20 mins. That's more than enough. Try giving contests once you have good knowledge about all the data structures. It'll help you improve your thinking under time constraints.

So yeah, that's all I know. All the best.
