TinyRick88 Congratulations for the job !!!
Things you mentioned are true & realistic.
I worked as Junior Linux Administrator in Pune, India for a Small Scale Company.
I know it was not a development job , but the part you said about staying confident and explain yourself in an interview is absolutely correct.
I will advice my fellow FCC Campers to complete challenges as something they really wanna do for improving their skills not only to complete the challenge and get certified.
Thanks FCC for everything you are doing.
