My own experience when I've been job hunting:
Agencies operating on a 'bait and switch' basis, advertising jobs that have 'just been filled'
Pushing applicants to apply for jobs they're not qualified/experienced in - and yes the job centre are the worst for this with the threat of sanctions. Eg I have basic it admin skills and basic double entry book keeping knowledge I was being pushed to apply for senior payroll and accountancy roles!
Being over qualified/qualified in other areas - I've a nursing diploma, I left nursing for lots of reasons and yet employers never believe I don't want to return to it. Couldn't if I wanted to now anyway.
Following doing uni a second time - thinking it would HELP I'm now definitely in the over qualified zone - but when I applied for graduate positions I was denied on guess? Lack of experience! That ones always frustrating as how are you supposed to GET experience?
As a lone parent since second time at uni I NEED to take tax credits/finances into account just to survive! If employers have a problem with tax credits maybe they should pay enough that tax credits aren't necessary?
Every job I've been in I've had good reports, good references, worked hard, happy to go above and beyond, do further training. I'm always smartly turned out, punctual (army raised its drummed into me!) and take pride in my work.
But I was also married to army, so I've a lot of jobs on my cv from moving around. That apparently makes me look 'unstable' and 'unreliable'. Before they've even checked my refs!
Agree re the part time over 5 days as opposed to part time 3 full days a week too, transport costs, childcare or carer responsibilities mean 3 days is generally easier.
Ditto 'but you can do overtime yes?' At interview stage - that's the employer equivalent of an interviewee asking about wage advances and early annual leave! It indicates an element of entitlement, trying to get more out of you than they're willing to offer in return before they've even offered you the job. I've learned the hard way not to take jobs where this is asked at interview because when I have those employers have been the type to take advantage.
I'm currently not working due to ill health and don't know when I'll work again. When I first left my last job my health actually improved within a year (at that point 'only' mental health issues).
The dilemma -
Don't mention your ill health and be thought lazy/feckless
Do mention your ill health and be stigmatised
Not just my experience I've a number of friends with mh issues or disabilities that's had similar reactions.
And yes also in the initial advertisement
Nonsense job titles that make a job sound out of reach to the very applicants that could do it.
Lack of clarity on pay and hours.
Either lack of clarity on the role and responsibilities - or an entire grocery list!
Expectations too high - offering nmw for the kind of role that expects you to stick a broom up your backside as well as do 200 other things! Even very hard working people will avoid this as again it indicates overworking/undervaluing employees.
