Am waiting for the 2nd interview to be arranged, was told that there would be one but that the director is very busy in the next few weeks so it could take a while.

Meanwhile I saw a job ad in the same ministry, and am wondering if I should apply as I'm quite interested. On the one hand, I'm afraid that it may be futile to pin all hopes on a positive outcome from this interview (don't think the other one went well!), but am also worried about hurting my chances.

Main concern is that HR may inform the hiring manager that I've just applied for another job in the same ministry and hence might not be as keen as I told them I was : /

Any thoughts?

Thanks in advance.
