I have recently started my career as SDE -1 (1 YOE)and I have been utterly disappointed to see that corporate is so unfair. Please please suggest some rules/guidelines to follow as I am finding it difficult to survive. This happens to me

Lived with one of my colleagues which was the wrost decision, we had to seperate. Helped the other colleague a lot but I got backstabbed, now we don't talk. Most grind work is given to me and I finish it too, others get far lesser and easier work. Others work is also given to me as they are unable to finish on time and timeline is strict. Got the least raise among my colleagues (particularly very disappointing). Handle more codebase than my colleagues. Have least exposure in my company.

I am too much confused and now I do'nt want to learn anything the hard way. Some plzz suggest some rules / guidelines in corporate world. What am I really missing that others have.

I don't want to become anti social person , but I am finding it hard not to.

P.S. Me and my colleagues experience/salary is around same.
