I'm a software engineer and I've been working at my current company about 6 months now. This is also my first job out of college and I'm only 21 years old. A friend of mine notified me that a person at his company is leaving the company and there is now a position open. Next week I'll be leaving to Germany for a vacation that I've been planning since last year, one that will take all of my vacation time: 2 weeks.
I like my current company, but it wasn't exactly what I wanted to do. My friend's company is much more in line with what I like to do, and I would be happier there and likely earn more money as well. I would burn a bridge with this company however if I left, after only 6 months and with all of my vacation time used. How would this affect my reputation and is there anyway to resign without burning a bridge with this company?
