First and foremost. Quantity does not guarantee success.
Most people who apply for jobs look for specific indicators they are qualified for, such as, junior developer, inexperienced ok, a beginning knowledge of these languages, 1 year university, intern. etc. Which narrows the job field they are applying, considerably.
If you just completed Free Code Camp and that is all, you have no other experience or education, you should not be applying for developer positions, only junior positions. If somehow you do get a job as an intermediate developer, it is very possible the company which hires you, expects you to be a lot farther along than you are. You could get the ax relatively quickly after your hired if this is the case.
So, with that said, most people pinpoint 5-10 companies they really want to be hired with which have junior or intern positions open. They spend all their energies creating a perfect resume, a perfect cover letter and a perfect profile specific to that company. In other words, they make it personal. Just generating a resume and a canned cover letter, with very little difference in them and submitting to 500 companies is exactly like playing the lottery. To me it is really a waste of time.
Case in point. The response I received just last week from a company I sent a resume through that I found on Indeed:
“It looks like you have very relevant experience to our needs and your cover letter was thoughtfully put together. Thank you for that.”
If I had not spent the time to tailor my cover letter and my resume for this specific position, I highly doubt I would have even received a response.
One way or another, they are going to test you. cPanel sent me a dev test, which I passed with flying colors, using recursion, bitwise operations, ternary operators, but I failed miserably on the in person interview when they asked me about specific technical questions relating to the language constructs. The language in question is Perl, and I was not versed well enough in Perl to give enough correct answers. So I was removed from the pool of applicants, even after I passed the dev tests, the first interview, etc.
Most companies have a 4-6 step interview process. The current company I am courting, I have a screen share with there lead dev tomorrow. The initial phone interview went well, now they want to see if I can back up what I said on the phone.
It is very easy to get initial responses from companies. It is very hard to get actually hired. I receive initial responses almost 100% of the jobs I apply for, yet somewhere through the interview process I fail 80% of the time. You should concentrate on applying for specific companies which have specific needs, specific to your talents.
Just my two cents.
Hope all the best for you.
