I interviewed at the union today

God I was so nervous. I'm 25 and I want this so bad. Overall it was a good experience, they said I did good for my first interview. I was recommended to get my EPA 608 (I'm trying to get into HVAC) at the mock interview I attended 2 weeks ago and I wasn't able to get it in time, I felt really bad. I told them what I had learned and they said that was really good considering I didn't know it existed 2 weeks ago. I don't have any on the job experience, my dad had been with the union for 20+ years, but times are so tough I don't know if that will mean anything. There's 160+ people on the list and they said only the top 15ish will get called in. I had three letters of recommendation from the time I've spent job shadowing my dad. I don't know, I'm so so nervous. I highlighted my knowledge of what the job entails, my work ethic, and my reliability. They said I'll find out where I'm at on the list in May, it seems so long.
