Once a litigator, always a litigator. Stay in your caste layman. Maybe in the next life if your karma is good, you may join a law firm. For now, stay where you are. You deserve it.
If you are willing to tolerate bad treatment and rudeness, then at least as a brand name, Vaish is a place which is easy to get in. T1's usually do not hire unless there is solid experience.
frankly, u cant just "become" a corp lawyer . It's like switching from medical to engineering. That will take some serious doing and frankly, not worth the effort. U can try compliance or dispute resolution instead.
Pls mention some names which will take people like me and pay decent salary to survive in Mumbai.
