You are applying for jobs that demand less - shall we say, a lot less - than the education you have. Should a prospective employer be concerned that you won't bail out on them once you land a job that's commensurate with your educational level and whose pay more closely matches the pay of those new hires that are in your field of study i.e. EE?
"i would love to work for your company" is not original - a jaundiced prospective employer would surmise that you said the same thing to the 49 employers you wrote before you wrote to him. And he also gets that pick-up line from many of the 200 candidates who apply for the position you are applying for. Nor, given your level of education, is your line coming across as overwhelmingly credible. You need to take head-on the issue of the disjoint between your education level and the skill level of the job you are qualifying for. Unless you make an argument to your prospective employer for why you want the job, and you make it credible and compelling in terms of your prospective employer's self-interest, your attempt to reach out is most probably toast. What should you say? Figure it out - After all, applying for this kind of job was your idea.
I could apply for a job at McD but given my background, my candidacy for the job would simply not be credible to a McD franchise owner. Employers want to know if you are going to perform well and whether you are going to stick around. Sure, the level of employee turnover in a shoe store is sky high - It is pretty rare for me to visit a shoe store and see the same faces four weeks later. However, you are asking a prospective employer to consider you, even as the prospective employer knows with almost clock work certainty that you are going to bail out on them. That's a tough sell.
I expect that in the last Great Recession, there were a ton of well educated individuals who were desperate for ANY job, given their financial situation. They never had a chance for the low skilled jobs because they could not make the argument that they were going to stick around with any kind of credibility.
Your chances of a successful candidacy are probably much better with jobs that are more demanding and that more closely match your educational level.
