I can sympathise, having a shed load of experience coming from 8 bit home micros, modems & electronics & over 20 years of desk side support 1st\2nd & moving into tier 3 at times.
I got a contract position, the recurryment agency that wanted my Ltd company details & registration details on receiving & accepting the offer urgent urgent urgent we want you NOW.....
Then they decided they wanted full background checks email conversations went like this:
Where did you do your degree - I haven't got a degree, I never stated I had a degree, I have a HNC in Electronics engineering its "near equivalent vocational" grade to a degree, only more practically biased.
How long were you on it - It was a 1 year full time course.
So you never actually completed the course - Did you even read my last email?
Can you give us your course tutors name & contact details - I don't recall them & even if I did he's probably dead by now.
After weeks of now no employment, no start date etc.....I got a interview out of the blue, for the following day & was offered the (permy) job verbally on the spot.
Three days prior to the start date, the recurryment agency\end client finally decided, contacting me by phone to inform me I could start the following Monday "generously waiving" the things that they couldn't verify beyond the last 8 years.
I'm sorry but I have tired of waiting for a start date that was supposed to be within a week & you\client have dragged out to nearly 6 weeks of pointless email exchanges going back over 30 years of ancient employment & academic history, leaving me in a state & expense of setting up a ltd company & giving my notice, thus without wages.
What? How can you take another employment? - Very easily as you have left me high & dry while asking questions that I have no reasonable expectations of getting personal references from beyond the grave & it has been over two weeks since I last heard from you in any follow up capacity. Goodbye! /end_call
Email arrives the next day..........
It occurs to us that your new employers will also be following the same background checks to ours, this will take many many weeks & you will have to wait for your start date. we recognize the inconvenience you have suffered as a result of the delay, so we can offer a rate increase of $3ph to compensate if you will start Monday - They did their checks in less than a week, took my word at face value & have gained my loyalty & respect, while you have evaporated yours into the wind. I gave them my word I would start with them, you gave me your word for a start date that rapidly disappeared into the ether with unreasonable expectations, I leave it to you to explain to your client why I will not be starting on Monday & please refrain from contacting me in future about any employment opportunities..
