Why SDE-1 with 2-3 YOE? You should push for SDE-2, my coworkers with 1.5 YOE got that.
Did your coworker first receive SDE1 offer which he pushed for 2? Or was he extended SDE 2 directly?
Your co-worker did better in his interview. This guy didn’t. So he received SDE2. If you only want to join as SDE 2 , tell it to recruiter and they will again interview you in 6 months. By that time you should have improved in your current role.
