Related to this previous question - in essence: I was taken on for a senior-level strategic type role but then after a few (about 3/4) months of carrying out that role (not due to performance) I was taken into a project team (with no known end date but will be at least a year in the future) where I am working in the role of a junior C# coder which is a step-back of at least 10 years in my career. (I am getting on for 20 years of experience!)
I've asked about alternate assignments etc and been told it can't happen due to the importance of this project to the company. They know that they are now paying me more (as the intended original role) than they would be paying a junior coder and they accept that. (the differential in salary is "nothing" compared to the amount of revenue that the company can potentially gain from this project)
Understandably I'm now looking for alternative roles... My question is how could I present/word this "interlude" to a potential new employer when asked why I'm looking again so soon (about 6 months)?
I'm not a "job hopper". I'd happily stay a few years at least in a job that suits me and I suit the company -- but at this company which claims to value self-development and such - I'm just stagnating now. I wouldn't have taken this job (I left my old company voluntarily, wasn't laid off etc) if I'd known the role would be "junior web developer" rather than "Architect".
ETA: the info is in the linked question, and the Q related to that, but adding it here for clarity: All my time is accounted for with "billable hours" etc. as the assumption is the "junior coders" are directly working on stuff for clients (the software I work on isn't the "product" for the clients, but it's a business-to-business model and our software enables various stuff they do using our website) (so I can't just study on my own initiative in work hours) although I am salaried as such. I could work on personal projects outside work hours, and have done for many years actually, but I'm suffering a strange kind of "reverse burnout" where I actually want to be doing more... and can't seem to get motivated with that. I feel like I'm about ready to give up actually which I haven't felt in all these years!
I suspect that it's partly due to me being "across" a lot of projects in the company, and so on the balance sheets as an "indirect cost" rather than if they recruited someone to do this work directly which would then be a "direct cost" to the project and as such it's political. I don't think I can overcome politics like that, especially since I'm relatively new.
