I just started a "dream job" for a big IT company. I was hired to be responsible for their market strategy for in the territory. I was previously covering the whole region, and I was told that once I developed the strategy, it would be applied to all of the region, and when the position opened I would be the most suitable candidate.
After starting, I realised that:
there is already another team covering the (greater) rest of the region, and they already planned to hire somebody for next year. This team is complementary but independent: I would have to change manager to cover the region.
there is already somebody else in an independent division of the company, who is responsible for strategy in that division; my manager asked me not to replicate his efforts, which means that I will effectively have to execute his strategy.
I was told I would be building and managing relationships with key stakeholders over a number of years: I was immediately approached by salespeople telling me that I would not own any relationship, and shortly after that my manager told me that "I will be to busy to manage any relationship anyway".
The way things are, I am being technical support for salespeople, indirectly following orders from my equivalent in another division.
This job is not what I was told during interview. I want to believe there are professional ways and appropriate processes to get formal commitments to the nature of a role.
Independently from where I go next, which steps do I need to take to prevent this situation from repeating?
