When the requirements clearly mention fortran, FEM and structures as
keywords then this should clearly tell you if you fit the requirement.
If these 3 things are not even mentioned in your resume, don't bother
sending your resume. You are wasting your and others time!!
Understand this you will get a job by earning it not begging for it.
So if you see yourself begging, you have already lost it.
And earning means fitting the requirements in skills and knowledge.
So stop throwing your resumes at every email ID you see.
The equation to understand is meet the requirement = get the job
The first part is in your control, so take charge.
