Pros
Working in this company will bring you so much pride. You will get enough exposure to different subject areas of your field, industry standards, best practice, etc. Great place to learn.! Job openings are posted internally, so there are many opportunities to explore.
Kontras
When you have already signed your contract and agreed to the salary presented, its a dead end. My advise is extend your asking salary to the maximum before agreeing to sign the contract. They will really give you the minimum of the minimum but once youre in, they will give you bunch of workload, requirements to fulfill, tideous task, and overtime time pay is not allowed. My colleague got promoted after so many years of working on the same position but salary increment is funny. The reason for the promotion is to align with the pay range of the job level. Better to look for a promotion outside the company.
