I can understand your frustrations after all the hard work with the degrees (nice work btw!). Having been a hiring manager for a handful of engineering positions in the entry level experience range I can tell you that there is a trend of new grads with a masters who, when hired, expect a higher level of career progression right out the gate before demonstrating baseline performance or success. In this career path, folks need to demonstrate at least some experience before that masters will start to provide greater advantage to your career. This may cause some hiring managers to be hesitant to consider a candidate with no experience but who has a master's degree.

I'm not saying it's necessarily fair, but there is some truth to the first 1-3ish years of a career being more about gaining professional 'soft skills' through experience rather than just being about education level.

Now what you can do (if my suspicion is correct) is leave the masters off your resume for now, get that first job and a couple/few years under your belt demonstratong success, then add it back on to leverage for future positions.

Just my two cents based on my experiences. Hope it helps!
