I did my PhD recently and it took 5.5 years to complete. I had just 2 courses in my PhD, so the timeline is excessive owing to my lack of motivation during my 2-3rd year.
I have also not taken any advanced graduate level courses in my PhD and am entirely relying on my publications for portraying my quantitative, technical and programming experience.
I had changed my field from materials engineering (undergrad) to mechanical engineering during PhD. But, I did not take any courses to address the lack of technical background (advanced mathematics and computational fluid dynamics).
My research was not that rigorous programming and technicality wise. So, I kind of survived through it. Studying other publications, self studying concepts through books was enough.
But now, since I have graduated, I am finding it severely uncomfortable to apply for positions that seek a different more rigorous job description.
I think, I made some terrible decisions along the way. I should have taken the courses as that would have built up my confidence.
On top of that, I have no job experience or internship experience. I have lost hope on academia and chances in industry appears slim too.
I have 6-7 months of a temporary gig to regroup myself and survive from imminent unemployment. Hoping for some perspective and advise?
