I do wonder how seniors manage cultural / technical differences. If the junior is not responsive to guidance, advices, hints .. what else do you do
The problem could also be with the senior.....
talk to their manager. If their manager doesn't respond you go to your manager or the manager's manager.
let them fail and see if they change affect
If juniors ignore guidance and advice, they stay in junior roles, handling simpler, less impactful tasks.
Everyone seeks career growth, but pushing for it too quickly often just leads to inflated titles without real substance.
It’s perfectly fine to remain a mid-level engineer for your entire career if it makes you happy; it’s solid, honest work that contributes meaningfully. Plenty of people in their 60s have held the same job for decades, and that’s okay; it can be a path to genuine satisfaction.
