<human>: Here is some back story on the situation at hand. I applied for a diesel mechanic job for a unionized rail road. My application was accepted and I was invited for an interview / drug test / written test / per-orientation meeting last Tuesday. By coincidence an ex-coworker of mine was also present. There were 7 other people there. They were only looking to fill 3 positions. 

I felt things went really well. I passed the written test. My answers during the interview were short and to the point. At the end of the session the HR rep told us she would be contacting us via email within a week wither we got the job or not. 

Well, it's been a week and I haven't heard back from them. I called my ex-coworker and he told me he got his rejection email yesterday morning. He also told me they were asking about me during his interview. So I'm thinking this maybe a good thing (well not for my friend :( ). But I am at a three way cross roads. This is where you come in Reddit, what should I do? I am thinking my options are

1. Dress professionally and go down to the HR department and talk to her in person.
2. Send her an email.
3. Call her on the phone.
4. Do nothing. (The suspense so far has been killing me.) 

This job would be the best position I have ever held. Working for the union, with a good salary, benefits, retirement plan, the works. This is the best job offered in the town / area I live in. So as you can tell, this is very important to me and I don't want to mess it up. 

I have been viciously checking my email, spam box included. Also she was very very insistent that we would be contacted within a week.  

Thank you for any input you can offer :)

Can you give me the gist of the text in a nutshell?
<bot>: Had an interview for a good job, HR rep said she would contact us in a week / pass or fail. Haven't heard anything yet, wondering what I should do.
