Hi buddy. I did the same thing. I graduated in 2019 from Delhi University then sat for 2-3 mains of judicial service and after failing in all of them eventually joined in house. I worked in house in reliance for a year then switched to boutique law firm. You can also make a switch but let me tell you law firm lawyers have a prejudice towards in house since they are accustomed to work 9-5(in house). So if you don't get direct entry in tier-1, then join tier-2 and gradually scale up the ladder. Work is good but timings are demanding. You will learn in both positions. In law firm you will learn faster as you will put more hours. Jo jitna time dega vo utna seekhega. Good luck.
