Hello student I suggest you for now focus on your academics instead of thinking about placements once your academic graph get a high its not tough to get placed in company like Google and amazon all you need some skills.For example, if you're hoping to land a software engineering role, a degree in Computer Science or something similar is useful.
Do a quick online search to find colleges near you with the program you'd like to study.
If you can't earn your degree full-time, consider studying part-time or online.

Feel free to comment if you have any doubt
Good luck
