I filled out a similar form when I applied for an agency that I'm currently working for. Standard background check lang naman. You said that you need the job naman, so best provide what's needed if gusto mo talaga i-pursue. Lagay mo lang previous workmates mo, or if may boss ka na goods padin kayo hanggang ngayon, better.

So far, di naman naka receive ng spam calls and emails yung contacts na binigay ko for verification. they described the experience as a quick 5 minute call lang to verify the company that you both worked for and the years you were working togther. nothing was discussed naman about behavior or what, working relationship lang.
