I got an e-mail letting me know that I've passed the phone screen and I have been offered an on-site interview with the company but the email informed me that they expect the interview to last 2.5 hours. It's essentially for a sysadmin position which would be a promotion for me. So I'm at least excited to be interviewed and see more about the company and what they're like.
However, I fairly recently started at my current job and it's one of the busiest times of the year for them. I'm not sure how I can possibly take 3+ hours(after accounting for commute etc) off on a work day, especially when I don't have any time accrued that I can use (I'm going to an out of country wedding in October so I can't use what little time off I have in case I don't get the job). This coupled with the fact that my current company is pretty swamped I'm not sure what to do here.
