Joined a company I hate the most

So, today was my first day in corporate. Joined a company that i hate the most, the government job company. During the induction itself, I experienced shitty HR (including all their internal depts) policies and their shitty rules. They literally told new joiners that they are going to force associates to take up the project, no matter what tech stack you want to work in! what domain do you want to work in!

Now, you may ask why did i join them in the first place? Well, the current job market for freshers is just too bad! Graduated in may 2023, spent past 4 months trying to get an interview, but never landed any (when applied with referrals HR said they want 4+ YoE, and also the struggle to get referral. got 2 replies on an avg per 40 DMs (<500 followers) per company, that too after expiry.) In the past 1.5 years, I've cracked OAs and tech rounds of fintech like phonepe and juspay, but final rounds went south due to ghosting and a bit of politics from the college side (i know this because I had some friends working for placement officer and also i confronted that officer). Hence, 4 jobless months led me to join this organization.

Please help me structure plan to get a good offer and leave this organization in 4 months.
