Should you go for computer science if you aren’t interested in it?
The situation in India may vary from my experiences, and the situation in times of a pandemic may vary from my experiences. Therefore, it is unclear how definitive any answer to your questions can be. But these are my two cents:
You should not go for any major that you're not interested in.
A degree from any of the fundamental sciences sets you up for many interesting jobs. From my math class, every one who graduated and wanted to find a good job, did find a good job.
