Sp I tried interning in two firms, I got stressed out by working for long hours everyday. I come from relatively privileged backflip where I don't have to support parents, they in good gov jobs. What can I do as a fresher which gives 9-5 work? Will in-house hire me ? If yes, what do I intern in for in-house

Snowflake ! Leave law ! It's more than 9-5 for every place in law. With this attitude, I genuinely advice you to go for MBA. Atleast your overtime will be compensated adequately better than law. Law is, and was, never supposed to be about the enormous money like STEM. It's more about the passion. Don't be a paper pusher and go litigate, atleast in a few years you'll have the freedom to choose your work timings accordingly. Still will never be 9-5 ever.

Start applying for internship in companies, think tanks and psu etc. It will give you a clear picture of your calling. When you intern in companies, please make sure to make direct connection with the HR and legal head or any person who has the power to take people in. Don't work like just another intern, try to reduce work of other members. That way they might give you ppo.
