Multiple Interviews (with TJO)

I have a TJO for a FDA position and CCHQ is going through my application now. I don't expect anything to go wrong on that side for the interview/medical.

I'm continuing to get interview offers for other positions (FDA/IHSC). My question is should I take the interviews and do I tell them about the TJO?

To be honest, I just need a job so I don't currently have a strong opinion on which job I think is better than the other. I'm afraid with the ever-changing political climate and job-cuts that putting all my eggs in this first TJO is not the safe bet. But I don't want taking on multiple interviews to ruin all my changes either.

Anyone have thoughts?
