Congratulations!
Reading your story reminds me of my first job. My search was a lot easier than yours. But you have reminded me of my feelings of uncertainty before I got hired. Though now, I just remember how much I loved my first job. And how it led me to great career. Then a series of enjoyable businesses.
I hope you will be able to look back in 50 years and be happy to see where your first job took you. Graduating was hard. But the real hard work starts now.
