Congratulations on getting your certificate! I’m still working on it… I think xD
As for tips, there’s one. Don’t give up. If you like coding, if you like front-end or back-end or any sort of web development, don’t give up hope and keep looking for a job. Try some freelance work if you can - it can help you build a portfolio. Having a portfolio (especially a decently sized, well made portfolio) helps tremendously.
Other than that - be ready to be denied without a reason, it happens. You may get your first offer after your first interview, that also happens. I’d recommend not being too picky since it’s your first job. If it is terrible, think twice, it may not be worth it, but usually 1st experience is the most important to add that “year(s) of commercial experience” to CV. At least in my country, it is the first thing any HR will look for. If you don’t have enough years of work, they won’t even consider you. Could be different elsewhere, but last time I checked this was a problem in the entire IT sphere…
Best of luck finding your first job! And again, well done with your certificate!
