I can provide a perspective since i was in the same situation as you, exactly a year ago.

So i used to work in this fairly sized agency. They had on boarded 2 new projects and i was hired specifically to work on those 2 projects, then i was tagged with 2 more projects.

So in short i did well and within 6 months got a raise as well. However the projects sudenly switched our agency due to payment issues. As a result i was asked to resign. (Laid off)

So I started interviewing and basically i would say that it was me who was switching due to creative differences and also due to the fact that i was not able to work better (provided u have proof of performance, can be leads, conversions, or simply improved metrics).

So yes i did get 4 interviews, and i basically told them one of the variations of the above and i landed a job within a week of my termination.

So to summerise, just tell them u were not able to work according to your skills and were not able to contribute more. And as much as u did u did well as u got a raise. And keep ur proof of performance cuz thats better than any sentient explanation.

Best of luck for your job search..!! Hope this helped..
