Guysss fked uppp

So i had my siib interview today n guess what i was sleep deprived already. They told to join by 11 30 but started by 1. After the gd i had to wait for 2 hra b4 my pi which was at 4 15. I was sooo exhausted n tired, didnt even eat lunch n then in my pi i messed up basic questions like currency of Japan, commerce minister, defence minister. I had learnt all this but i cudnt answer a single question n the panelist just said ok bye. I m really so pissed cuz i knew i cud do better but this long process just exhausted my brain n i cudnt answer even tho i knew. Idk what to do anymore yaarrrr i wanted to get in siib. The ge too was like a fish market idk mann .😭😭😭😭😭😭
