The application process is very detailed. We too had many detailed sessions with assessing sw. Some would say intrusive. At least two hours at a time. Birth to present day.
Some of it bordered on marriage counselling. All of our 4 (adult) children were interviewed as were both our referees. We had to provide all my addresses from birth (I am in my 50s). When I pointed out I couldnt remember my first couple of addresses as I was under 4 I was told my application could not progress until they were provided. I mention this to demonstrate how inflexible (some would say idiotic) the process can be.
Similarly employment details ie full details of dates employers addresses going back to age 16/18 etc even though they may have moved/gone bust etc. The joke is that if you say self employed that is good enough to cover any period. No evidence required at all to back this up. I mention this to demonstrate it is not an effective process to cover everything for protection of children etc. It is just a highly self important, over officious process that ironically is easily usurped if someone is motivated to do so.
There was a comment above
"It's also very clear that you don't understand the system (social worker doesn't make the decision about approval for a start) so your contributions are really not massively helpful. "
I must disagree with this sentiment. Although the assessing sw may not make the final decision their comments and conclusions will normally carry the decision. I have been made aware of some truly appalling statements and comments from assessing sw often in areas that they have no training and expertise to comment. The assessing sw wields enormous power. Piss them off and they will get their revenge. (this is a feature you wiull recognise if you go on to be a foster carer !) .
The assessing sw is interviewing you to assess your suitability for a career. They are not your friend, they are not your confidant. They arrive with their opinions, they will judge you. Often unfairly.
I would not recommend lying but you are entitled to some privacy and given the choice I would present a vanilla impression rather than the full knickerblocker glory account ! Please dont assume anyone has a sense of humour or express extreme political or social opinions.
To give you an idea of how detailed the report is that is produced ours was 89 pages.
Answer the questions but be careful about volunteering too much information that isnt asked for. You may feel it is helpful and will enhance your application but it may well harm it. You are playing a game where you don't know the rules.
In summary the assessment process, in my opinion, is not about you proving your suitability but rather proving you are not unsuitable. This is a crucial difference and is the mindset that all applicants should have.
