>Do not disclose the current status of your interviewing process
Not sure exactly what this means but it's pretty common for recruiters to check your timeline and try to work around it. For instance, they'll try to expedite you if you already have offers on the table or relax the timeline so it fits with interviews.
I strongly recommend only sharing minimal information about your job search with employers. Don't share when you started looking, because if it's been a while then you'll look bad. Don't share that you think you're far along in the process at some other place, because if that falls through then you'll be embarrassed if it comes up again or it might look like you were lying to put pressure on them.
The fact that an employer could speed things up for you if you have active prospects elsewhere is a little insulting because it's the flip side of saying we know we can put you on the backburner because you're unemployed and struggling.
You can say whether you're actively or passive looking, or if you have a firm offer on the table, or if you're especially interested in employers in some particular area if it makes you look good with this employer. Otherwise don't bring your search up and politely deflect questions if you can.
