So I graduated from my Master's in Electrical engineering 8 years ago, with a good CGPA of 3.75/ 4.00 and three conference publications (with around 15 cites) along with my job which is only tangentially related to my master's research topic (MS topic was in Controls, job is of embedded systems design). I am really passionate about doing a PhD in my master's area of research but am finding it really difficult to get admission, especially in the top-tier universities. Have managed to get to the interview stage but rejected and mostly given the feedback that I have a long gap without recent publications. I have started to get disappointed now, does the academic world not take on PhD candidates with a research gap like mine? I mean I am still in a research and development based job so I am not totally out of the process of conducting research? I always mention the technical and soft skills that I have gained from my job in my interviews and personal statements/ letters but it seems professors don't want mature candidates anymore.
Any advice or feedback is welcome. What countries should I target with this profile? I personally feel Canada and Australia favor fresh candidates more but I might be wrong.
