Trending @Accenture; Stuck at career🤒🤕

I was in a project from last 2 years where I was doing no actual development. It was very easy tasks basic repeated improvement and debugging tasks and comfortable, I was very happy also those days and went under the comfort zone, that's where I made a mistake now my actual skills didn't improve these 2 years. Although I got good hike and promotion but what's the use now my rolloff date is near and current project has no requirement. And I am not able to crack new projects as I am getting development project calls due to my own paper skill but I have not brush up those skills and it's been ages since I did actual work related to those skills. And now...how my project client interviews are going my confidence is getting low day by day....feeling stuck.
