I got laid off recently and one of the things my company did was to pay for some sort of job placement/job coaching sort of service.
It was useful. Basically, talking to somebody just help me focus on the stuff that I knew I needed to focus on.
They did have sessions on Interviewing where you could do mock interviews and they had sessions on resume writing. And you could send your resume in to their service to get hacked apart/edited.
Personally, I got the most value from a session on "LinkedIn" and a session on resume writing.
I've been on "LinkedIn" since 2004 but had been working for the same employer for the past decade so I didn't really have my LinkedIn presence updated. That helped a lot. Got lots of recruiter interest after that.
But, the main thing is to use your personal network - something which worked very well for me.
The problem I had with my resume is that it had slowly grown from 1 page in 1994 to 5 pages by 2017. So... for 2018, I did some hacking and slashing to get it down to 4 pages. One page intro and 3 pages of detail. I'd still like to get it down further but, I got a job quickly so... it'll probably wait.
Hope that helps. The main point of a job coach is to probe you with questions to make sure that you're thinking clearly and that you're staying focused. Not just taking the first job that comes along.
