Thank you!

The manager's email just asks me whether I'm still looking for a job and whether I would want to work for them, but without actually attaching an official offer in the email yet.

If I follow what you said, should I also ask for an official offer right now and tell them I will get back to them asap? Something like this: "Yes, I would love to work at XYZ but I'm currently waiting to hear from company JFK and will gladly get back to you as soon as possible, at the meantime, could you please provide an official offer via email?"

What do you think?

Thank you once again.
